My reading comprehension is fine. I'm well aware you're an urbanist who hates sprawl and cars and loves density and transit. You need to work on yours, because I never said that you like sprawl (in fact, I said the exact opposite: "You may personally hate sprawl for various reasons"), only that urban growth boundaries raise the cost of housing and that "NIMBYs", if they were motivated by increasing their property values instead of concerns over the character of their neighborhoods, would support policies like urban growth boundaries and upzoning because they result in a reduction in the supply of houses and an increase in the potential land usage value. You argued that they loved a shortage of housing because it increases property values, and I pointed out that the reality is more nuanced.

How are you any different that the someone who doesn't want an apartment building built because it would change the character of the neighborhood? Both of you support policies that increase the cost of housing in the hopes that everyone will live the lifestyle that each of you prefer. You prefer multi-family housing and want people to live in it, and support policies that make it expensive to live in single-family housing. The hypothetical NIMBY (who is, as mentioned previously, not someone who is purely interested in maximizing their house's value) prefers to live in single family homes and wants it to be expensive to live in multi-family housing. I'm sure you'll reply with some handwavy thing about sustainability and externalities, but the NIMBY can similarly bring up crime, noise, congestion, and other issues with dense living. There is no difference other than which housing type the two groups prefer.

I would be less hostile if urbanists like yourself would just admit that they want to force everyone to live their prefered lifestyle instead of hiding behind bogus economical and questionable environmental arguments. If you truly just wanted the option to rent apartments then there would be no need for policies like urban growth boundaries. Removing both the zoning rules and the boundaries would allow for housing that people want to be developed, but what would you do if your neighbors make the "wrong" choice?
