It actually does (kind of), the problem is that the gap between "not profitable" and "affordable" is a chasm. Someone who is currently paying $350/week rent with minimal savings behind them (which statistically is an optimistic assumption) is not going to be able to find a 10% (or maybe higher) deposit on a $500,000+ property.
The other issue is that right now we're experiencing massive inflation of house prices. Median house value in NZ increased 24% in March - that means you'd need to save around $2000/week just to not lose ground. It's madness, I'm glad I bought at what I thought was the top of the market in March 2000.
You could even do a construction project and bill the land lords for that directly. In an even crazier universe they would get something in return for the [forced] investment.
House prices will go down, and more people will be able to buy. For others, there is public-ownership rental and even public housing (that would be of much higher quality than today)
How is that any different? If it's more difficult then it inherently consumes more time and/or money - given that money is (arguably) how we measure the value of labour I don't see any way of escaping this.
