I think this is reasonable as well, and I wasn't trying to imply it is wrong. My goal was to point out an asymmetry in the system and to give a little more insight into the "homeowners vote, non-homeowners don't" observation of the GP.
And it ultimately seems like politicians have more to fear from the immediate prospect of losing votes from NIMBY constituents than the potential gain of future votes years down the line from grateful new residents.
