How does mandatory single family zoning and parking minimums factor into your "feature?" When people want to live somewhere dense, and that's illegal to build, they're forced into suburban living even though that is not their preference.
> When people want to live somewhere dense, and that's illegal to build It's not illegal to build everywhere. That should be obvious since there are lots of dense urban areas. I could just as easily ask why I'm not allowed to build a new single family home in Manhattan. The obvious answer is that Manhattan is not a suburb. The equally obvious answer to why you can't build dense urban housing in a suburb is that it's…
Meanwhile, regardless of land price, dense housing is illegal to build pretty much everywhere that is not currently dense, due to zoning laws. Why shouldn't someone be able to build dense housing in a suburb?
What it sounds like you advocate for is that everywhere currently dense can stay dense, and everywhere not currently dense must stay not dense. That doesn't make sense unless you want the dense area to continue to skyrocket in price as more people want to live there and we have no new housing to accommodate them.
