Why don't they just get rid of the process?

Hold a referendum to elect the constitution. Assuming it passes, you select a commission of people in charge of it. They get absolute power over anything relating to property - eminent domain, changing zoning laws, and giving building code exemptions.

It would only work if there's a democratic majority in favor of it, but if it did, what would be the issue? Then it would be very simple: just buy up some land, start building, and rezone anyone who complains as heavy industry and evict them.

I'm of course writing this in jest - hopefully they wouldn't have to be that draconian - but why hasn't anyone tried this? Is there not an electoral majority?
