I’ll say one thing, if this thing leads to remote work becoming much more common, people are going to leave these big cities in droves. Rural areas are going to see a big population increase.
The high cost of living, taxes, and now increased risk of death, will not make these areas worth it.
NYC metro area is very densely populated and to be honest, I don't know what anyone could do with that place. There is not an arms length of space as everyone is on top of each other.
CA and TX have done a decent job trying to keep folks away from each other for the populations they have. Houston is a very large city. Saying is, that when you are in Houston, your are still 2 hours from Houston. At least they are spread out, hoping it makes a difference.
Mardi Gras just did New Orleans no favors
