The "poor" people are extremely poor to the point that you cannot comprehend. And they have to stay there and live there for their entire lives because the current system forces them to. It is impossible for them to move out because of how unaffordable the cities are and how heavily the system is rigged against them. They have nothing. These people are already commuting long distances and already live in unregulated, unmarked ghettos. Here[0] is a photo of one of those places I took back in March so you understand the extent of it.
The only people who "lose" here are the current land owners of legal properties. Renters will end up with lower rent because housing will rapidly devalue to a tenth of its original value - every single house will stop being the foreign investment opportunity that it currently is.

Clearly it's not retroactively applied. Town planning and zoning almost never is.
> It also bans building a house with a courtyard on a lot below a certain size.
I mean, I guess? But it also forces properties to have back and front yards, as well as side access, instead of being 100% concrete built wall-to-wall through to the footpath.
> This wouldn’t help poor people. It would just force them to commute to their work from further away.
I'm not sure how it would do anything else other than help poor(er) people and allow them to start living inside expanding cities rather than living on the extreme outskirts.
