every time the government alters the fair-market price for things, a transfer of wealth is created. sometimes for the better. but yeah, in every case, someone is getting boned.
at least this is only addressing the past and not creating upside-down incentives going forward. if the state said they were paying off any delinquent rent going forward, then only a fool would pay their rent. although, I'm sure a lot of people are making a mental note for themselves to stop paying rent the next time there is a state of emergency.
