That's my point. Falling victim to alcoholism is not an apt analogy to getting a covid shot. People don't generally choose to become alcoholics. If you really want to make your contrived example fit, it would be something like a shot that prevents organ damage from alcohol, not desire to drink.

If such a thing were available, and people refused, and then got alcohol poisoning, then it is arguable that, on some level, their stupidity is to blame here.
