Triple health insurance premiums for people who refuse to vaccinate, like car insurance companies do when you get caught driving drunk. We can keep our precious "bodily autonomy" while still making sure reckless behavior is costly.

Not opposed to it, as long as the premiums are actually reflect the probabilities and cost of the harm. You words like "precious bodily autonomy" make me think you are looking at this from a pov of malice though, as in, let's try to financially ruin people.

How so? We already require vaccinations for other diseases and it’s clearly been effective against them.
