My local public golf course was closed and sold to developers a few years back.

Promises were made to the community of keeping all the trees and lots of green space, as there was vicious community opposition.

The developers have of course instead done what you suggest, and every house is crammed in next to each other just like every other new suburb. Its still in progress but it looks like once they're done you wouldn't even know it used to be a golf course.

This meme is so stupid because it doesn't present an even remotely possible outcome. A far better option is to keep the public golf courses for people to spend time outdoors and to provide homes for wildlife - and then remove regulations limiting building heights to encourage multi-storey development.

Build up, not out - because once green space becomes houses it never changes back.
