Why not just let the market cater to the those different preferences instead of government fiat dictating a single construction type?
Because the market you are talking about is tiny (when factoring in that NC Condos is not gonna be cheaper than existing SFH and maybe not even small NC SFH). Except for The Poors, which is what the NIMBYs are afraid of.
Explaining to people that are unhappy because The Rent is Too Damn High that NC would be even more than that is something that's hard to get across.
