Any/all government is force.
The question is how much force, and when is it justified.
The regressive damages from covid-19 have been truly ignored by the loud antivax crowd. Though I definitely recognize the regressive impact of a mandate, and have noticed other people do as well, there's a gist of people throwing in that argument to supplement that they themselves don't wanna get vaccinated.
I'm sure they will throw in anything they think will help them get away with it. But if they started claiming that wearing a seatbelt as justification for not getting the vaccine, that doesn't mean you should stop wearing one.
I believe too many people are very significantly underestimating the legal and long-term ramifications of a mandate. Especially in the context of a disease/country where (almost) everyone who actually wants a vaccine, gets a vaccine.
Refusing to cover people who're mainly the victims of misinformation is the absolute height of bad governance.
Do you really believe that? Coming from governments that themselves spread misinformation (I include US and Canada among every other government here)? People are misinformed about health generally. They are also misinformed about laws, financial investments, and other life-ending or ruining tradeoffs. Governments, both yours and mine, *routinely* "refuse to cover" people who are victims of misinformation or lack of knowledge, across a wide range of spectrums. They even give in to lobbies to extend the degree to which this happens.
If we honestly, truly had governments that cared for the truth and well-being of the populace, we would see a lot less federal mandate/direct intervention and a lot more public announcements/informational spending backed with sources. Even now, I wonder if the policy of "mandating by executive fiat" has actually performed better than, say, spending that same money or even less on pushing out information about the disease/vaccines and normalizing the COVID vaccine to other vaccines to more people. "Anti-vax" has magically taken on a new meaning in the context of COVID...almost like most people who hesitate over COVID are not the same tiny % of people who refused any/all vaccines previously.
Rather than having big tech lock down information and using executive fiat, maybe such normalization would have afforded a better rate. Instead, we have politicized garbage where initially the vaccine was a "Trump" thing, until it wasn't, and somehow the change in political backdrop changed (partially) who wanted it vs not, as if the nature of the vaccine itself changed along with the politics. Ridiculous, but not unpredictable.
COVID is a nasty disease and shouldn't be taken lightly, but it is absolute peanuts compared to the examples you're quoting. I believe you were trying to refute his point, but the above more so supports it. If COVID were 10-15x more deadly for people who contract it, and reliably killed a large % of adult working populations, it would be plausible as a nation-destroyer. That's not what we've observed, though, in contrast to those historical examples where ~25% or more of people who got them died (in the case of smallpox in western hemisphere, likely MUCH more).
