I agree that it's depressing that people don't realise the power of collective action. It would be lovely to see in labour markets or in rental markets for example.

However, the sums of money and level of commitment involved in starting a new city are radically different to that in buying a bit of GameStop or Bitcoin or whatever.

Even if you chucked in ten grand your friends might think you're crazy.

By contrast that's not even getting you half of the materials of a house. Or an apartment. Even if it's a prefab with no interior. And we haven't even started talking about making a city yet, what with all of the roads and power lines and decision makers and those juicy bits.

It's actually just a far harder problem to solve.
