"In the long run, we're all dead" -- JM Keynes

These are buildings we're talking about. A city can get stuck with the wrong size units for a very long time. There's a reason things like the Parker-Morris space standards were developed, and they recommended 30m^2 for single occupancy dwellings in the UK in 1961.

The 220ft^2 apartments are 20.5m^2, not very large at all. The really tiny ones have communal shared cooking areas, which have the potential to be a social problem.

I think people are terrified of some kind of Stand on Zanzibar future where they're economically constrained into smaller and smaller spaces, and this is one way to push back.
