I don't know where you live, but where I am, housing is expensive. As someone who is paid pretty well, I didn't want to make things worse for those who don't earn as much, so I helped set up a YIMBY group. We've had some modest successes. TBH, donating is pretty good too, as it lets people who are a bit more specialized in doing the work get on with it, rather than training up someone who 'wants to help'. Depends a lot on the organization though, I think.
