I'm all for more housing, but at least theoretically I'm on the fence about this. The example (17 => 1) is "not optimal", but the ability to buy two adjacent strata properties and merge them solves the "2br condo vs suburban house" problem. As in, the notion of "observed preference": that given that choice, people choose the latter, and so -- here's the fallacy -- people "want" the suburban house (and therefore that's what we should be optimizing for). Experimentation around the 'missing middle' (condo/townhouse with SFH square-footage/room diversity) seems very much a work in progress.
