Is this meant to argue against a limit on the quantity of properties that one individual can own? If corporations were not permitted to own property, and other individuals were allowed only two properties (what real need would there be for more), the quantity of available property for purchase would skyrocket. The prices would plummet, and far more people would be capable of owning their home.

I don't disagree that there is disincentive for developers to build mid-level properties. They want huge expensive homes or the ability to cram many people into one space. I think this is a problem, but is not the only reason for the lack of availability, as described by the grandparent and in my former paragraph.
