This is an excellent take on the intracacies of where to build housing.
The "capitalist model" does indeed address supply and demand issues. However I feel it breaks down when the market is globalised and housing is used as safety deposit boxes rather than actual places to live.
London is a peculiar in that the communities are propped up by the renters. Having lived here all my life I have gotten used to communities changing hands every 5 years or so.
It's beyond me why housing security isn't more of a thing here for those with jobs crucial to a thriving local community - e.g teachers, healthcare workers etc.
It's apparent that what we have isn't a fully liberal capitalist market, but a game of monopoly.
