That is just ignoring even the most basic economics. The quantity isn't relevant without price. The problem here isn't economic sophistication so much as few people other than timr seems to have actually read just a normal economics textbook and understood what it actually says. That most of his comments are downvoted without relevant rebuttal just shows that.

>“The quantity isn’t relevant without price”

The price depends on the quantity. Price is not baked into the walls, but comes from market conditions. How you can deny that and then claim the high ground about understanding economics is beyond me. This is incredibly easy to check: physically identical homes go for wildly different sums in different markets.

Timr argues above that 1) construction will take time, and 2) it will only continue as long as it’s profitable. No disagreement there. We need to be planning for the long term as well as the short term, and profit margins have a long way to fall before reaching zero.

No, what he is essentially saying is that far earlier than you can produce enough housing so everyone can live in the bay area, the cost of production will be higher than what people who want to live there can afford.
