The problem with an antipathy to a market solution to home ownership - if you can afford it you can buy it - is that alternatives are authoritarian.
Do you want an official telling you where you have been allocated a poky flat?
Also, the presumption here is that if you are lucky enough to be born in a beautiful seaside town you have a right to live in it all your life. So if you are born in St Ives, bingo! However, if you originate from the sixtieth floor of a high rise, there you are stuck forever. This seems inherently more unfair than a system where law and the pursuit of capital through aspiration and endeavour enable anyone who wants to do so to strive and choose where they want to buy.
In the past it was always the case that youngsters struck out from home to make their fortune and, if they made some money, and wanted to, they could return home and buy.
If you read your eighteenth and nineteenth century novels, access to homes was a primary concern for everyone. Try some Thomas Hardy, Dickens, the Brontes or Jane Austen. It will cure the modern sense of entitlement behind the idea that, 'if I have children here in this rural/coastal idyll they must be housed on my doorstep.'
