1) Individual behavior changed prior to the lockdowns (people don't want to die)
2) The government appears generally too incompetent to figure out how to lower R0 low enough to eradicate the virus
3) Since everyone can see that the govt is fucking this up, the marginal utility of hard lockdowns becomes less than the marginal pain. Some people will socialize, go to restaurants, etc. but...
4) It probably won't be more than a 50-75% return to normality because people don't want to die, and risk preferences vary so some will remain cautious. This will, crush small businesses, restaurants, bars, leisure, etc.
So since the govt is too incompetent to bring the virus to actual 0, then formal lockdowns don't matter because you're not getting rid of the virus anyway and raising them doesn't matter much either, because you're not going back to normal.
