Can you speak to this:
The density will grow, and since individual construction companies don’t have an incentive to care about urban planning, just their own projects, you will get ugly neighborhoods and questionable infrastructure. There’s no guarantee that this will happen, but I’ve seen it happen in my city.
AFAIK, every major city developed like this. If anything, there seems to be evidence that absent development planning you get organic development which leads to massively desirable places to live (NYC, LON, SF)- where almost all the existing constrution was before significant zoning restrictions.
This isn’t necessary. The half life of free CV is estimated at 1-2 hours. While it’s true that CV DNA can still be detected after several days, this says more about detection technology than CVs virulence. After 12 hours we’d expect the number of active virus particles to be reduced by over 99% rendering the risk very minimal.
