It's not necessarily prices falling here but the profitability of [demand] at [price]. Like if prices fall 10% but demand rises 20%, you would want to build more housing.
This is the beauty of the free market because it guarantees three things:
[1] Real estate is generally a good investment and will hold value or appreciate in the long term, because supply will adjust to demand shocks to rescue values
[2] If people want to live somewhere, houses will be built for them to live there
[3] Real estate developers and construction are solid, safe businesses with great unit economics because building may decrease prices, but may still increase demand
It's when you constrain and restrict a market that players have to adjust and then you get crazy scenarios
