I am sympathetic to making it easier to build, but we have to be honest about the trade-offs that have been made in some of these hyper dense asian cities. Namely, ugly buildings, and lack of green space.
It's also worth noting that these places rely on significant, long-term, investment in public transport infrastructure of the kind that they don't make in the US. This is something that's often missing from the debate.
Edit, I think people are misunderstanding my comment a bit. Personally, I'm favour of making it easier to build housing - I don't own property because it's too expensive and would love it to be cheaper.
I'm merely saying that I've seen a strand of thought amongst the right/wing VC crowd who believe in very aggressive liberalisation (pretty much build anything anywhere), which I don't think is practical or politically feasible.
