The homeowners are making rational choices. That's the problem. As the most expensive asset a typical homeowner will ever own is their home, it makes rational sense for them to support any policy that supports it's value and oppose any policy that undermines it's value. Building more housing undermines it's value.
And this is why the local community absolutely should not have any more say about a new development than a hypothetical someone who would like to live there, but can't, because there is no available housing.

If you start giving "hypothetical people" a say, you stop having democracy. You can invent as many hypothetical people as you want to force any outcome.
And real democracy requires local control. A distant democratically-elected government making centralized decisions may just as well be replaced by a tyrant, given how unresponsive it will be to your concerns.
The "hypothetical people" are in actuality all the other voters in your country. Lots of people are "pro-development, just anti-development near themselves".
Do you think that the Japanese system where permitting is centralized away from local government antidemocratic?
They're often terrible at knowing what helps or hurts values though.

no it doesn't, high density allows more value to be extracted from the same plot of land since the volume of units offset the individual price reduction of each one. as a result, developers regularly offer homeowners 2x or 3x their market value to incentivize selling.
Yes, it more efficiently utilizes the land. But, if you are not the person who owns the plot that gets developed, more housing being built next to you harms you.
