If they can really get the economics of scale going, this has broader implications for long term disaster relief, poverty (not extreme poverty unfortunately), refugees, and climate change migrations. Cheap, robust, and easy housing has long been a goal for architects. Bauhaus has it's roots in German communist housing for the masses, after-all.
Would prefab housing really help with poverty when the production is suddenly offshored?
Prefab backyard homes could be part of the solution - and at scale could make a big difference.
"... gains vast insight from the Airbnb community to thoughtfully respond to changing owner or occupant needs over time"
to me suggests Airbnb believes their long-term future requires more than ignoring zoning laws and city regulations; it requires changing them to suit the company's goals.
There's nothing wrong with seeking to change laws but we should really look hard at the underlying motivation. Is it to make housing cheaper/better/more plentiful or is it to increase the number of airbnb listings?
Wouldn't it make more sense to look at the effects than the underlying motivation? Why would you care what the motivation is?
