I did not say demand exceeds housing technology carrying capacity. I said if the peninsula urbanizes (i.e. denser building, maybe 2-4x, not mega skyscrapers with bunks) demand will keep up. That should not be an extraordinary claim, given how many bedroom communities and commuters already surround it.

Why are you limiting the possible technologies? Skyscrapers work.

Housing is a cost of living. Driving the cost of being alive as low as possible should be a high priority. We should use the tools we have to do it.

Because I believe they sacrifice quality of life for density, and I think we can do better.

We don't need to pack everyone in like sardines. As you already noted, there's plenty of space in the world. (You just have to turn your eyes outside the peninsula).

P.S. I do not live nor aspire to live in the peninsula, or anywhere near it

Why are you limiting the possible technologies through government regulation?

No other city is full because at some point people decide not to live so tightly packed together, and demand dries up.

Current laws raise prices to enforce low density. That's wrong.
