And what exactly is the problem with depressing commercial real estate value? Personally I only see upsides for the economy. Incentive for people to try to do productive stuff instead of holding to their precious real estate and collecting rents, possibility for entrepeneurs and companies other than megacorporations to actually open stores in cities...
What's the problem with abandoning ACA health insurance mandates? Plenty of economic upsides there, too. You really can't see any possible unintended consequences with sudden punitive tax conditions on commercial real estate investments?
