You've got to be careful with the idea of 'freeing up labour'. This assumes that another ten+ per day opportunity exists
already (the units are apples, you're either picking more apples or fewer apples. They get picked or they rot.), but that the field owner is going to tax all-but-ten. There's no guarantee. But there will
always be lower-value jobs. The lower you go, the more they are. A MW destroys 100% of them. Two kids ask to shovel my walk. If they insist on $15 per hour each, because that's the law, then they don't get hired. Reductio ad absurdum, sure, but it shows the point. The labour and the opportunity are both there. If it gets priced out of the market, the job doesn't get done. Heck, I cannot even go work my 'living wage job' in order to pay for the shovelling. Because I'm better at shovelling than they are, there's no comparative advantage trade. I go to a church, and the usher offers to show me the seats. I find out he's a volunteer, so I leave. They're not paying a minimum wage, even though he's providing a service. The teenager next door offers to walk my dog while I am at work, I say 'no' because it's zero-sum. I have to work an extra hour to pay for the one hour of walking.
In all of these examples, society is better if the service happens rather than not. In fact, in all cases a
mutually beneficial arrangement is possible, but forbidden. If my time had been worth more, the trades could have happened.
So, the damage is being done regressively.
I made a quick mistake in my analogy, with my government example I was suggesting that it's very easy for the government to create a 'job' that involves picking one apple (but paying ten),
and thus crowding out the opportunity that allows picking two. The two never get picked because someone is wasting their time picking one. Keep in mind, I'm comparing it to a UBI. In a UBI, you get ten (or nine, or one, whatever. It needs to be phased in). Then, if you see an opportunity to pick one, it gets picked. You might not pick the one. But you might pick the seven or nine. You might pick 100. But the two can get picked, because it's not priced out by the one. In the real economy, people who have 'a living wage' might still have side-hustle. People with a living-wage will still work on for a charity or community organization. So, we know that a portion of people will seek out opportunities to harvest those apples. The UBI frees up more time.
But don't only think of jobs paying less than a living wage as being a 'drain on society'. The job already exists. And if it's not taken advantage of, the opportunity is lost. Now, obviously, if that job isn't sufficiently productive the worker needs subsidy. But with a MW
only the employer is allowed to pay the subsidy. Teen living with his parents? No one can take advantage of that subsidy. His wage is zero when it could be nine-per-day. The retiree on a pension? They can't leverage their subsidized life, even if nine-per-day opportunities exist. Their cost is still ten. They're already fully subsidized.
Part of an economy is just simply lost opportunity. Part of an economy is the acquisition of goods and services that make a long-term shift in future costs. For an example of the first, an economy where people can afford to go out for dinner tomorrow is literally 'better' than one where people cannot afford to go out until three days from now. The ability to dine tomorrow is an apple that can be picked. Even if people can only dine out once a week, being able to do it sooner than later is 'better'.
I'm a worried a too-expansive job guarantee is a bit like the welfare trap, even. In our current welfare trap system, you get a welfare check that then gets clawed back (potentially at over 100%) if you go find any work. We've known about this problem for decades but are terrible at fixing it. You get welfare of $14k if you cannot work. But, get a part-time job, and your welfare either ends or you lose a portion of the welfare cheque in proportion to what you independently earn. Thank God people work under the table, they are not the villains in this story.
If the government were hiring people to produce nine or eleven apples, that's great. And government spending is VERY capable of hiring people to pick wayyyyyy more than ten. It's certainly
possible. But there are mechanisms in place where people assign a limited budget and try to create value from that budget. With a jobs guarantee, I worry that you've unhinged the budgetary mechanism a little too much.
I'll show a quick example where a job guarantee ruins people's ability to seek more productive opportunities.
This article actually covers it really well

If you look at people's retiring patterns, you'll see that people drop off after they've done their four. And then they flee once they've done their 20. The entire article is great. Instead of people leaving as they perceive opportunities, once they've done their ten they end up doing their 20. From 5 to ten, they leave if they see a better opportunity. Now, it's a wage guarantee, not a job guarantee that they're sticking around for, but it's the same idea reframed. The high wage (but low productivity) priced out higher productivity opportunities. You know it's true, because people flee after they get their 20 to get better jobs.
Keep in mind, I'm arguing against a minimum wage because I am insisting that a UBI is better. The MW destroys opportunities. Output and creation is less than what it could be. The field owner who's able to get 20 picked per day but can pay one is taxed on the nineteen in a UBI. And the workers get eleven (10+1). As soon as they see an opportunity to earn
2, they will take it.
Anywhere. With a MW, there's a field owner with nine apples per day. If he pays 8, there's still a profit. If the MW is ten, they rot. With a UBI, he pays two. But Mr.20 is able to then up his bid for the labour. Mr.9 cannot compete with Mr.20 on wage if there's a MW.
You think it's great because all workers are getting paid at least ten. Except that the person who only needed 8 and will only pick 8 is getting zero.
From both fields, that person is still getting zero. Heck, the person who only needed 2 and can pick 3 is still getting zero. From both fields. There's more room at the bottom. Always. But the MW is insisting that people's minimum wage is zero if it's not ten. The person who can pick only nine is a drain of ten instead of one. The MW is insisting that there are more fields are available where people can pick 11+, if this is true, it's just as discoverable with a UBI as with a MW.
A society has to be
lucky for the MW increase to lead to an aggregate improvement. You're hoping that the local multiplier effect (which comes at a zero-sum cost with the customer or people further away) outpaces the opportunities that are regressively forced out of the market.
