The author of that blog has some good ideas.
For the first one:
Instead of like now, only allowing ever larger and larger developments to happen in and around cities, it is time to start dividing them up into pieces large enough to be handled by organic, human scaled, individuals or groups of individuals
How would a city do this?
For the second one:
“How do you build a town?”
Most town were developed by pioneer just stoping in a spot and building a home. Then more folks came and built more homes. Soon a form of city services was needed. Now it is a city or town.
Other times it was a developer who sold lots. I live in such a situation though it was called a HOA rather than a town.
I would love to hear how others feel about these two situations.
