Corona is basically endemic in the US. You can test nursing homes and airport arrivals, and do followup testing on a small population. You cannot test 320 million people, and do followup weekly testing on them.
Perhaps you're inspired by the success in NZ or Taiwan. The US has a totally different situation.
You seem to think that "doing something" is better than nothing. Again, that's false hope in this case. Herd immunity is the only logical result in this case.
But hope is not a strategy.
I would compare the US response to corona in 2020 to the English and French appeasement of Germany in the 1930's. Denial of reality resulted in the total destruction of Europe in WW2, not much different to the health and financial results of corona.
