I generally agre with you, but you're using poor examples. Getting a free vaccine that requires nothing more than showing up someplace is not comparable to obesity, STDs, or addictive drugs e.g. But the rhetoric of "they only have themselve to blame" is wrong.
Even suggesting unvaccinated people should be fired from their jobs (thousands already have been) or scapegoated (is that a word?) in health care is not okay. (Denied health care sounds like a human rights offense).
I would, however, like regular covid-19 tests for health care workers to be mandatory. Especially among the staff at elder care facilities.
If we are making "excuses" for fat people or addicts on account of mental health, we could make them for the anti-vaxers too
What about people who get injured rock-climbing? Nobody NEEDS to go rock-climbing, do they, all you had to was simply not engage in a frivolous and risky behavior. Yeah, no two things are exactly identical, then they would be one thing, instead of two things. But there are still similarities.
No one serious ever says that, only random foolish people on the internet. But sure, it's a secret government plan right before they put the unvaccinated in concentration camps.
Alcoholics can't get liver transplants because they'll ruin the liver again, and that's as far as that argument goes back in the real world of public healthcare.
Yeah, hence "testing balloons" and not "official policy". Let's not play dumb and pretend that we don't know how these things work. Kimmel is not a random 15-followers fool on the internet. This is kind of a No True Scotsman combined with reverse Slippery Slope fallacy. It's just a massively watched tv show host, it's just a random party member, it's just a bunch of congressmen, it's just the undersecretary, it's just a minority of cabinet members, it's just a temporary executive order to flatten the curve, it's just a bill. Well yeah now it's a full-blown law, haha, oops. But you had no reason and evidence to be alarmed before and you were totally crazy and paranoid the whole time.
I'm not sure what the liver transplant bit was about. It's proving my point - that almost always we do provide health care to people who brought the problem on themselves through their action or inaction.
Smokers pay a premium on American health insurances as I am sure you know. Everything else you say is about risk vs benefits for actions that are not necessarily under people's control. People can be obese because of genetics as much as behavior, mental health can play a role in addiction, walking outside is a necessary action and on average not that high risk etc.. There are some people that genuinely can not be vaccinated for health reasons and those obviously should not be penalized in any way. But for the others there absolutely zero rational reasons to avoid getting vaccinated.
Generally speaking, I have no problem with premiums for smokers and I would have no problem for premiums for fat people, addicts, or anti-vaxxers as long as they are justified by insurance math and not a thinly-veiled punishment for its own sake.
There is the metabolic syndrome, that makes it hard to lose weight once you reach a certain level of bodyfat, and the absolute dog**** poison that is allowed (by the very same FDA, no less) to be sold as food is to blame too, but 99.99% of people who balloon up to 30+% of bodyfat do so through overeating and lack of movement. If you have negligible energy expenditure and you eat three, four thousand calories a day, it can be the cleanest, most raw and organic food in the world, but you will become obese all the same, just over a somewhat longer period of time. How many hospital beds and man-hours are spent on all the heart attacks, and diabetes complications? And not only are they not denied any health care, we even have a massive obesity normalization media campaign going on.
There is absolutely zero reason for people to do a lot of things that they do, but we still respect that they people are ends in themselves, and therefore endowed with autonomy to do dumb things. Sure, the autonomy is not infinite, but things like (de-facto) covid-vaccine mandates, let alone the, yes at the moment hypothetical, denial of health care to the covid-unvaccinated, do not pass the proportionality test when compared to other behavior that we do allow.
