We need some free-for-all zones to build new cities. I know with the current political structure it's near impossible, but "Hamsterdam" from the wire ( uhh, sans drugs and killings... ), comes to mind. A libertarian paradise. Perhaps it could start with more landgrants on just a fraction of the massive bureau of land management reserves. Free from entrenched politics of existing cities, these zones, if done well ( technocrats, here's your chance! ) could serve as inspiration for exporting the know-how to the existing cities.
You might like to read the book “A Libertarian walks into a bear”. It’s about a group of hardcore libertarians who took over Grafton New Hampshire with the goal to do a small town version of what you’ve described.
