> Free use comes with responsibility: whoever occupies a home must keep it in excellent condition and cover its ongoing maintenance costs. If you can’t afford to properly maintain a particular home, you can’t occupy it
Exactly who decides what constitutes "excellent" condition? Exactly what do you do with people who fail to keep their home in what whatever authority figure considers to be "excellent" condition? If I really want a property somebody else has, can I trash it right before inspection day or pay off the inspector to declare it non-excellent? What do you do with the poor hard-working family who just doesn't have the time or money to keep their place in "excellent" condition? What do you do with the mentally ill person who trashes their place every other week and can't afford to fix it?
> For desirable homes or plots, anyone can apply during a fixed period. If demand exceeds supply, the new resident is chosen by lottery, regardless of income, wealth or status
Lottery? Riiiiight. There's just no chance a simple lottery system will be able to manage the issue of to what extent particular homes or areas are desirable. There's no way a lottery system massive enough to even attempt to address the issue will actually be free of influence by wealth and status.
> The country must always keep at least 10% of homes/plots available, creating real choice and mobility
Exactly how is this going to work in practice? Which "10%" is going to be kept available, and how do we make it available? If we have a desirable city center with under 10% free, do we have to kick some people out to keep that 10%, or do we kick some people out for a while to build denser/taller buildings? Or will our "10%" only be in the undesirable areas?
If I'm a rich person, can I pay off a poor person who happens to have a nicer house to move out to a somewhat less nice house so I can move in? What if I say, I'll pay you to voluntarily move out, or I'll pay someone else to trash the place or pay off the inspector to get you kicked out?
Nobody is smart enough to dream up a new system in 10 minutes that actually covers every possible use-case and situation more fairly than our current capitalistic system that has existed and had all of its rules in practice and iterated over for hundreds of years.
