But that additional housing can also destroy the character of existing areas. That doesn't mean we don't build, just that it has to be considered, which is harder to do when demand is increasing too quickly.

Sounds like preserving character is the real zero sum problem then.

Complaining about both the rapidly increasing housing prices as well as the loss of character in developed areas doesn't have any cognitive dissonance at all, though.

It's a balance, one that AirBnB is making far more difficult to maintain.
