That's a fact about policy choices, not something that can't be changed. If building housing wasn't illegal it would be built. Developers love money and the Green Belt is quite big enough to spare one Mnahattan's area if it was politically possible to build a Manhattan's worth of housing on it.

Ok but now we’ve moved from ‘bicycling is relatively practical’ to ‘it’d be relatively practical if only everything about our politics and built environment was instantly completely different.’
