I think land use restrictions are an important part of the equation, but they are often asked to carry too much water. Also, land use restrictions aren’t always what you think. Public parks ARE land use restrictions. Central Park is a restraint on supply. Arguing for a pro-development agenda doesn’t just mean easing height restrictions, and I’m deeply suspicious of the pro-development enthusiasm that seems to crop up among many urbanists. Not because I support intensive land use regulation, but because I don’t think that enthusiasm will last when faced with real, significant examples. As soon as somebody wants to build a skyscraper overlooking the Capitol, I think most DC YIMBYs will become NIMBYs. Honestly, I probably would too! So I’d say I agree with the folks who want to reduce land use restrictions, but I think their enthusiasm is insincere and naive.
