No one is proposing rent control in a vaccum. Arguing against that idea is disingenuous and is how you end up with the status quo of “rent control is actually bad for renters” that gets parroted in economics circles. State intervention is necessary for markets to exist in the first place and they have overwhelming power in shaping them.
Building large scale affordable public housing, incentive structures that promote the building of affordable high density private housing, banning corporate ownership of single family homes and short term rentals like AirBnB, limiting corporate ownership within apartment complexes, reworking zoning laws to better suit current needs, more robust mechanisms for tenant disputes and transparency for historical rental prices to prevent abuse.
All of that is possible if the political will was there.
