I've been mulling this a lot for a while now. I see so much vacant space and wonder how much of a boon it would be to small entrepreneurs and communities if the market were optimizing for filling a larger share of rental space. I suppose it might be disappointing if the rents dropped and all it lured in were payday loan shops, and I imagine any tax enough to effect behavior will also induce some landlords to just fake occupancy to dodge the tax without the liabilities/risks of an additional business running onsite. I'm a little skeptical (but maybe not pessimistic?) about how plausible it is to engineer public-benefit outcomes for this kind of space?
