I understand the desire to do something like this, but we are not going to get it at all. We should be staying away from these new "crazy" ideas, just because they look like it could be huge, doesn't mean they will be, it's just opinions of some people who wishes for it, but there is no data or proof that suggests it could work.
Maybe we just haven't gotten much real testimonies about this innovation enough to drive interests of people to invest their money into it especially as we all know how hugely demanding real estate investment could be financially and as a result people wouldn't want to risk their money in such large sum into some new ideas on the go.
If I am to go into real estate investment, going cross border in a tokenized form would be the least to do for now despite whatever barriers that be said of about traditional real estate investment it doesn't sound risk to me as tokenizing does.
