In my view it only does so incrementally. At best you can double properties. Society would benefit more from joining lots to create a footprint for multi family dwellings, rather than dividing them.
But a lot of people are willing to make tradeoffs, e.g., the younger people passing through town, the elderly, and the poor, all have different housing preferences.
We are bending/slowing the insane growth in SFR prices and slowing/ending homeowner displacement.
As we scale we'll make a meaningful impact, but the solution to affordable housing is not just loosening artificial supply constraints, and is bigger than any one private (or public) organization.
