Probably need to zone some of that agricultural land (60% of land usage in the netherlands) into housing, if we want to give young homeowners a chance at owning property.
It takes more than houses; also entertainment, food, infrastructure, jobs, etc. Otherwise, you're 100% right, location is king and nobody wants to move away from a fun/profitable/valuable city to live in an abandoned mining town in Oklahoma just so they can own a home.
As dystopian as it might sound, I wonder if there is some way to "crowdfund" or "preorder" a new township location. Everyone signs up, pledges like 1,000 USD or something with a lease extending at least 3+ years. And developers can use that money to build an entirely new township in a location with cheaper land. This might help alleviate the problems that come along during a cold start with requiring critical mass adoption before a location is desireable to live in. (Not suggesting this exact course because having an entire town owned by a single developer sounds like a capitalist hellscape; just thinking out loud, I don't know what the actual solution would be)
I believe something similar is already happening with something like the Culdesac project. (I have no affiliation with this project, just so happen to live near it and have heard about it a few times) : https://culdesac.com/

This is also an interesting point in the article. Was it actually a scam or just overly ambitious and poorly executed?
