it's crazy that people nowadays seriously question basic market pressure being a thing

Yes, it describes human nature better than psychology. We can’t fight even knowing about it.

There's loads of other inefficiencies as well. Moving is a huge hurdle. It's difficult to find housing that meets dozens of conditions, and even then you don't respond to supply + demand imagined equilibrium, you pay more or pay less to live near friends or family. It's something you only do a handful of times in your whole life. Trying to use the same analysis as for buying a can of beans is absurd. You might need to take econ 201 before you understand why econ 101 is wrong about housing.

the snark is quite rich when reading beyond the headline makes clear this was anything but a free market solution.

They also teach you about elasticity in econ 101. It's foolish and anti-intellectual to insist that the housing market has only two factors, while simultaneously condescending about your understanding of economics shows that you really don't understand economics, it's more about your ego.

I don't think this is simple econ 101. Yes with more houses we should expect lower prices, but also with high prices we should expect more houses produced. All that is econ 101, but that second econ 101 prediction isn't happening. I would guess that some will chalk it up to vaguely (though not necessarily wrong) jerks/idiots blocking it. Whether it's because nimbyers want to keep their home values (what we should expect from econ) or it's broken city politics, there are lots of things going on here. It's more complicated.
