No public roads: instead, private encroachments that connect to one another. Each plot shares with the public domain part of its land, where all link with each other in a wandering path. Someone may be generous enough to add a pool or a garden to the mix, the least is a right-of-way. Therefore, you start by considering the others as part of. It is not communism, but rather an assertion that we cannot exist hermetically, and that we are part of a whole to which we contribute.
The public becomes a collective of privates.
