The point of the moratorium is not to affect prices; it's to give the city a chance to come up with a plan that will protect affordable housing in this one neighborhood, without losing the ability to act.

Viewed in that light, this report is a vote for the plan, not against it: it gives a little breathing room, and probably won't affect prices either way. Whether or not it "works" is entirely speculative: someone has to come up with an actual solution in the longer term.

I believe the advocates of this proposition want the city to buy the remaining vacant lots in the Mission, and use them to build affordable housing projects, but I could be wrong about that.
