>Why should it be everyone else's burden if they make a stupid decision to stay put in a place they can't afford? Is that a right?

Obviously utilities going up should be considered in rent, but in a property tax-free world, someone staying is not a burden on the owner, except in the "he could be making even more money". The owner ends up making less because they might not be market value, but considering that what he's doing is rent-seeking anyways, there's not that much moral high ground for the guy who wants to increase rent just because of "the market".

Obviously these problems are nuanced (and economists seem to all agree that rent control = bad )
