I mean, I agree with what you're saying, but it misses that abundance means abundance. Consumer staples should cost near the price of production, and where margins are out of control, the government should step in and end the rent-seeking... that is what abundance is. If we live in a society where there is no price appreciation in owning an apartment to rent because another apartment can be build next door, then we live in a society where your dollar goes further, and cannot be captured by the wealthy cornering the market.
What we have now is the opposite. We know that housing demand will rise in the future, simply because there will be more people. Instead of the rich investing in housing production to meet this need, we have the rich investing in existing housing because we have effectively stopped production, thus the rich can capture all that value in price appreciation from rent-seeking alone (technically more of it), instead of wasting their time operating a business that builds things.
I think that’s compatible with my take:
Be prepared to enthusiastically think of and promote the greater good (abundant, cheaper housing in this case) rather than protecting every single valuable individual thing (existing house value, amongst many other things, in this case).
> we have the rich investing in existing housing because we have effectively stopped production
In my quite affluent city, the most affluent neighborhood has yard signs up every fifty feet expressing that they are furious that the city might develop city-owned parking lots (which are nowhere near their neighborhood) to be high density housing.
One-bedroom apartments in the city center are going for over $3,000 per month.
The rich aren't simply locking up existing housing, their principal concern is preventing any housing from being created, even if it has no effect on them.
