Economists want a perfect supply-demand capitalist dreamland. Demand drastically outstripping supply indicates something is wrong with The System^TM and that’s not acceptable, so they want to fix The System^TM .
It’s clear the demand is there, so it’s not a consumer problem. The supply is super-limited and being reduced every day. That’s a supply problem. The only options are incentives (don’t really work in this situation) or regulation (which economists hate but no other choice).
I assume most economists just don’t want to see what happens when that system reaches an absolute breaking point, so sign on for regulations it is.
