Median age of Covid deaths? 75-84 years. https://data.cdc.gov/NCHS/Provisional-COVID-19-Death-Counts-...
This is on par with median age of death in the U.S. on any given year.
You cannot crush the future of your country to extend the life of the elderly by no statistically significant amount. I'm sorry, but that's the truth.
For 20-55 year olds, the core of the economy, this virus is not very deadly at all. This age group is far more likely to die from many other causes.
I would say, fix the nursing home problem. Ask the elderly to wear masks or shelter in place and to beef up on vitamin intake and anything else that would help their immune system.
Then, I would let the youth and young and middle aged adults continue life as normal, develop herd immunity, and therefore prevent a widespread infection next winter.

It is probably possible to do this and aim for eradication. This is NZs plan. It’ll be interesting once the borders are unlocked.
