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.
