This is a great point that really needs to be taken more seriously and it goes way beyond just Airbnbs and VT. What needs to be strictly regulated is rich people and private businesses buying up all the single family homes at a premium (so no one can compete with them) then renting them back to the would-be homeowners and Airbnbers at inflated prices. It's not just VT either. It's the whole fucking country minus the shitty places no one wants to live in anyway.
