I think the intangible aspects here aren't relevant because the original poster was talking about the financial investment aspect itself being a reason to oppose development. I completely agree that qualitative reasons will cause people to want to control development, and personally am fine with this, versus just letting the people with the most money dominate the market. For (D), though, I think this is generally overblown. There are no guarantees, and situations vary, of course, but trend-wise, I don't believe "partial" in-transition up-zoning has been a value-killer overall. In parts of the US that are densifying, these sorts of things are generally radiate outward from high-demand areas. But the single family homes in the high-demand city core areas still have more value than the ones further away, and if you look at the appraisal reports, it's because of the land value, not the structure. In the long run, that development cycle creates the demand that pushes up your own land value even if yesterday vs today, it was more attractive in isolation as a single family home next to another single family home. "Location, location, location" is a cliche but a valid one. As long as your location stays in demand - and in our current city planning paradigm that's not been something that's been threatened before potential post-COVID reorganization - you're more likely to hit a virtuous cycle for property value here than a vicious one. The types of developments/apartments that are gonna be put up are gonna be determined in part by how much it cost to get the land, so if it was already valuable land, building a slum next door won't make any sense to the developer.
