But they don't have the same access problem because the public squares don't have access restrictions.

I think the point is that private owners might run into the same issue of needing to cross private land to get to their private parcel.

		I understood the situation here to be that the same private owner owned all of the private squares in this particular area. I would assume that most private owners won't be interested in buying squares deep in the checkerboard for access reasons.
