Realistically, I can't argue with your point. It's like giving up. It's sad that many people won't take basic steps to help protect others (including themselves), but I guess that's a reality-check.
Those who are older, with multiple comorbidities, or are immune-compromised, listen-up: More than enough people don't a shit if anyone other than themselves lives or dies that you should probably just isolate yourselves from society indefinitely.
All the more reason to strongly urge people to get vaccinated. Clearly one can't count on neighbors, the community or broader society to take minimumal steps to help protect themselves and others.
So you're on your own, living life at your own risk. There is no "society", just you. Protect yourself and get the shots.
At this point, it's looking like 'mostly vaccinated' is the primary measure and beyond that we can live with it.
But there are important caveats in that 1) hospitalisations have been a problem and that if were didn't have vaccinations (which help a lot with serious cases) we'd be in a world of hurt so we need to keep up with the vaxxes (the antivirals are not a solution just yet) and 2) we need to accept there could be another wave that's worse than Omicron or Delta and that at least some measures have to be re-implemented.
