With or without airbnb, states aren't about to create anything close to a policy which compels existing landowners to rent out parts of their property. How do you increase housing supply?
Connecting two parties together to rent a place is no problem in general. But the difference here is that AirBNB has, until very recently, been extremely focused on short term rentals that walk and talk like hotels. Most cities ban rentals less than 30 days, unless it is a room in someone’s house or another dwelling unit on their property. AirBNB was great when it was filled with this, but as soon as multi-unit operators took over the site and it became filled with unlicensed hotels that flout the city bylaws, it went downhill and I fully agree that this impacted the supply and pushed negative externalities on everyone else.
1) Change zoning to actually allow mixed use and high-density living space instead of single-family
2) Fix tax laws and incentives so that property owners actually pay tax based on the real value of the property instead of whatever nonsense they pay today (California is especially bad for this, but the mortgage interest tax deduction sure as hell doesn't help)
3) Reduce red tape and regulatory bullshit that slows or massively drives up the cost of new developments
