To take this to its logical conclusion, once the streets are gone, there is no need for buildings anymore, so they can tear those all down and plant a forest. But then you wonder where you are going to put all the people who used to live and work there.

I spent seven years living in an apartment. I so enjoyed hearing the neighbors having sex, the thumping music they played, the smell of their cigarette smoke inside my apartment with all my windows closed, the random intrusions by management to repair something unrelated to my apartment, the random rent increases. Add this to the fact that I had no space for a work shop to make anything, and paying the equivalent of a mortgage with no equivalent home equity. Some people love apartment life, but it definitely was not for me.
