The covid response has really been a great reremovedtion of any right libertarian ideology.
Vaccine hesitancy is one of the largest externalities right now. Those that dont get a vaccine benefit from herd immunity (if we would ever achieve it), and have so much to gain from increased vaccination rates. They reap these benefits from others getting the shot, without having to get it themselves. A classic free rider example.
But worse than that, we see that there will very likely be an escape variant, eventually making all of this effort pointless entirely.

I checked on some libertarian forums to see how they would handle vaccines as an obvious and deadly externality, but of course they've entirely bought their own lies. "Vaccines are a personal decision, im worried about the government forcing me to get a shot, etc". Literally nothing about these extremely obvious problems we will face.
