I know the model from OP, and as far as I know, there is already something like that with real estate in the USA - I will not post any links, but whoever is interested should look for keywords fractional investment/tokenized ownership.
It is also very common that today real estate can be bought for crypto, there are dozens of websites that offer just such a service. So I can't agree with your argument that crypto has no place in the real estate market - but I can notice that you advertise your real estate website on a forum dedicated to Bitcoin, which is actually the complete opposite of what you say.
