Well, medicine recognizes both physical and psychological addiction.

I am aware of that and I don't really want to downplay psychological addiction at all.. it's just nowhere near as difficult to overcome as physical addiction.
Psychologically addicted to gambling? What, you have no free will? Stop going to casinos..

Why does that mean we should encourage "tax on the stupid" schemes, though?
The companies that profit from it encourage it.. And our governments themselves promote Lotto 649, do they not? I dunno.. I'm not really sure how I feel about the encouragement of such things..

Anyone operating a casino knows there's "X" amount of problem gamblers in the population. They consciously set out to exploit and manipulate them. Regardless of the individual morality of that cohort of "X" gambling addicts, there's still the question of the responsibility, limits and behaviour of purveyors of gambling. This is a policy issue, not a morality one.
You could successfully argue that McDonald's does the same thing to people who are obsessed with junk food.
We're all adults here (hypothetically speaking, assume we're all legally allowed to gamble), let's take some responsibility for our actions.

Should casinos be able to create gambling machines were you just swipe your credit card directly into the machine? Why not? It's their own responsibility if they do it, the casinos are just trying to make an honest buck!
Rubbish.
Why, are people mindless drones?
If you're stupid enough to max out your credit card on a machine like that, it's your own damn fault. What.. don't you understand how a credit card works, or something? Do you think it's free money?

Also, I'd appreciate it if you wouldn't demean and trivialise genuine mental illness like that. The fact that you "can't stop eating" potato chips, or whatever your vice is, is hardly the same thing as genuine clinical compulsive addictions.
If you truly have a biological chemical imbalance that causes you to go to casinos and lose thousands of dollars.. then I truly do feel sorry for you (not you specifically, speaking generally here). In that case you should go to rehab of some sort.. or at least put yourself in a situation in which you would be unable to gamble.. much like a heroin addict would check into a rehab and go cold turkey..
If you end up in a casino anyway, tough luck. Maybe you'll learn your lesson next time.
