It's the usual suspects denying reality and merely spewing their exact same debunked arguments that have been debunked many many times. They will never change.
These are the people that want to FORCE their preferred lifestyle choices on everyone else, and they are also the fuck you, we got ours, so screw you crowd by telling people what they can do with their land. And some are even progressives, all about helping the middle and lower classes and easing the pain of wealth inequality - except when it comes to the single largest expense holding the middle and lower classes down - housing/rent prices. Then they are well, fuck you, we got ours, and we are going to keep it that way at any cost. They could give two shits about the middle and lower classes, it's mostly an act.
A friend of mine had buyers recently. They had a home plus owned a full empty lot next to them. This is in a NJ suburb that has single family homes and some slightly higher density that is in two family housing, maybe a bit more in a small downtown area. Anyway, the buyers had a builder chasing them for a while to buy both lots, because he could build two 2-familly duplexes on those two lots. Higher end of course, since the housing shortage given to us by the 'i got mine so fuck off' crowd, makes it that builders have the luxury of only catering to the higher end market.
Anyway, they agreed to sell but only after they found a place to buy. After over a year of searching, they found the place they wanted. They were supposed to close on their sale in the morning, the new home in the afternoon. Well, five days before closing, the next door neighbor on one side found the builder and said they would do everything in their power to stop him from building next to them. Now the zoning was already there for allowing two families on those lot sizes. But still, because the power of nimby's with money is they will still fight that shit, the I got mine so fuck you crowd, and it would delay the project at best, tie the builder up in litigation, so he bailed on the deal.
This is what all the anti-housing and forcing their lifestyle on everyone else people have created. This insane shit show.
