Covid has long term effects, not all known at this time. https://www.cdc.gov/coronavirus/2019-ncov/long-term-effects....
Are you willing to have 5% of the population end up like me... short of breath, and pretty much unable to do more than 1/2 hour of physical labor per day? I can do grocery shopping, and that's it for me.
[Update] I used to be a machinist, on my feet 8-10 hours per day. I feel like I've lost 10-20 years off my life.
If 5% more of the population goes down each time they get it, you're going to run out of people.. just like Texas ran out of natural gas, when it seemed impossible.
Never underestimate exponentials, and long term effects of novel situations.
