The 1/10 perspective makes a strong claim about the price elasticity of supply of housing. It would seem to be testable, but while it's easy to measure elasticity in a controlled environment, for something complex like the market for housing, doing so might entail some assumptions that 1/10 economists don't choose to get on board with.
