He makes the case that we should allow high density towers because people want to live in high density areas near transit and jobs.
But that seems like a rather flawed argument, given that we do not have affordable low density areas near transit for them to choose.
People don't actually want that level of density, they mostly just want to live near transit and near to their jobs timewise.
If we built out reliable, two way, regional trains to other small cities, and built LRT and subway networks in them now, at their current sizes, then we would be able to see whether people actually want to live in high density towers, or whether they would choose lower density options.
