They don't want to end homelessness because then so many activists and organizations will be out of a job. It's a perverse incentive.

The key to tackling the housing crisis is to build more housing, particularly high-density housing. And to do that, zoning laws must be deregulated and liberalized, if not outright abolished in some instances.

But of course, the activists will never agree to that because it's a market-centered reform and because they are rich NIMBYs. More housing will mean the properties they own will decrease in value. The scarce housing supply and the continued existence of the homelessness problem is great for their own wallet.
