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

Real estate is NOT supposed to be a good "investment" and only became so because the government started propping it up with bank bankstops, zoning, NIMBY, redlining, etc. If your pricing is working correctly, real-estate should be close to zero-sum.
Austin, in particular, had several nasty bust cycles where real estate prices tanked after overbuilding which is precisely what kept the cost of living under control. Alas, that is a thing of the past after 2008 when everybody realized that the federal government will backstop the banks "Real estate number must always go up! Brrrrr!"
It seems to me that the market will select for urban sprawl though which is a negative for society but has the highest margin. E.g. Houston suburbs, miles and miles of cheap to fab single family homes that turn it into a suburban hell scape where you have to drive everywhere.
I don't think the free market is giving the promises you say it is - supply isn't elastic for real estate if nobody's building because there's no margins. Demand can be anywhere really.
I like to look to Tokyo for an example. Small lots, extremely predictable regulations (that are still strict enough to ensure a safe living situation), fast approvals, mean it's much faster and easier to throw up an 8-10 story apartment than say downtown Austin, and so even today they keep doing it despite land in Tokyo being very expensive. And, no sprawl.

Not as a developer you wouldn't...
You already have razor thin margins. Prices going down 10% means you cannot get financing for your project.
Holding real estate is generally a good investment. Developing real estate actually is not.

No they are not lol
