But the logic some people use to support these things veers into territory where it sounds like they would be willing to make (or demand) any sacrifice for literally any increase in safety. I worry about how that will play out long term.
But that’s just my fear. Hopefully it’s overblown (and it probably is).
Seems like you're strawmanning/shifting the goalposts, considering your initial comment says "I would just go back to living like I lived before", which would suggest you would take zero protective measures.
I probably would mostly go back though. Overall, I’d rather accept a more dangerous world with normal human contact than continue the kind of things we’re doing now indefinitely. But I’m sure I’d be more cautious about visiting a nursing home than I was pre-Covid. I’d be a lot more likely to isolate at the first sign of a fever than I used to be. I’d wear a mask when I’m sick. But I’d probably stop avoiding gatherings, masking when I’m well etc.
If kinship isn’t your thing but sober analytical thinking appeals to you, wearing a mask is a no-brainer: positive benefit with effectively zero cost (the only negative thing that can happen to you is that someone might think you’re a terrified dweeb, but they’d be wrong).
