It is unlikely the human instinct to both accumulation and ownership of a private space will significantly erode and that routine sharing of significantly more space currently treated as private will have widespread acceptance by 2030.

If the author just means "more people will live in condos with significantly more shared use infrastructure including cars" then sure. I do. But I also have a very strong clearly delineated private space, with my property in it. Even renters have defined legal rights to control (within limits) access to space and goods.
