Yes, one way we could fix supply/demand is by scaling up the density of detached and semi-detached neighbourhoods. This means mandating narrow one-way streets (6m wide) and banning wide two-way streets (15m wide), forcing smaller front yards (reducing setback distances), eliminating garages and driveways in favour of street parking, allowing narrower properties and smaller homes overall. Furthermore, we should be allowing mixed use zoning so that small shops, restaurants, cafes, and bars can serve these neighbourhoods and promote a walkable lifestyle.

These neighbourhoods can be served by light rail / street cars allowing more distant travel via rapid public transit, further reducing the need for cars. Look at a lot of the older neighbourhoods in big cities such as Riverdale in Toronto [1] to see what streetcar suburbs look like.
