That was already discussed by Greek technologist Andreas M. Antonopoulos. He said....which products or services can be traded with bitcoin? Answer is everything. And also who can have his own coins? Everyone! But people around the world have to accept the fact, that crypto currencies are already changing their life (even if they dont have a clue about it)

In 1950s....people were in same denial about credit cards as they are today about the blockchain. When they saw mastercard the forst time, they said : "this piece of plastic is not money! Get away!" :D

What I want to say is....blockchain is just making another step in monetary revolution. And sure....real estate will be tokenized. Like everything else. If government will not support it, people will still trade houses or flats in crypto currencies. Your name is registered in town hall only as new owner.
