I’m just confused about the argument you are making here - that if our options are:
A) let’s all get a couple of shots to reduce our risk of death, serious illness, and make it less likely that other people get sick, not to mention making it less likely that new variants will emerge by making transmission harder
or
B) let’s have no vaccinations and let the virus sort it out, like we did with, say, the 1918 flu? Or polio, measles, or smallpox?
or
C) let people get vaccinated or not, it’s their business, but putting societal pressure on them is overbearing and eventually pointless
That of those options we should choose either B or C? Because B is how we dealt with illnesses until we had vaccinations to make them harder to get and less deadly. Then we started…vaccinating people. And now measles is still a thing, but no one worries about it, except that cases are going up because people aren’t getting vaccinated. So B seems like a bad plan, because we tried that and it sucked, and then we did A with measles and things got a lot better.
C is certainly a lot more personal liberty-oriented, which I get the appeal of, but society is fundamentally about giving up some amount of individual liberty in exchange for shared and communal benefits. C is actually what is happening in some places with measles vaccinations, where individuals say, “I don’t need to be vaccinated because herd immunity will save me”, which not only means that (despite claiming personal liberty) those people are relying on the vaccinated people to protect them, but that they’re willing to put others at risk (because vaccines aren’t perfect) in exchange for their individual liberty. This seems like C is a pretty raw deal for the liberty and rights of the people who would rather not get infected by, say, measles. Or Covid.
B and C both seem like bad plans. A seems pretty good, but I realize you’re not going to be convinced of that. B is pretty indefensible, I don’t think anyone would argue we should just let Covid run through the world and kill millions and millions more people. Or maybe you do, I don’t know. Seems bad.
But with C, the only way you can argue it’s not selfish to look after your own preferences is if you believe that the outcomes of option A, B, and C are the same. That it doesn’t matter - the same amount of people will die, and the same amount of people will get infected, and the same amount of people will permanently lose their sense of taste or smell, and the same amount of people will end up in the hospital. That fundamentally the outcomes of all three scenarios are identical. But there’s no way that’s the case, right? It just doesn’t make sense.
So if there IS a difference, then A is everyone doing as much as reasonably possible to make things better, B is everyone giving up and accepting whatever happens, and C is valuing your interests above the opportunity to help others. That’s the definition of selfishness.
