This virus will probably be around and mutating forever, like the flu. It's impractical to try to avoid catching the flu virus for the rest of your life, just as with COVID. Sure it's possible, but that's no way to live.
I do agree with you about that being a defeatist attitude.
On the other hand, I wish we knew more how this is transmitted. People eating indoors isn't the main vector of transmission. And masks don't help much either. And eventually getting a booster every 6 months won't do much either
