I understand exactly what the comment was about: there is absolutely no way to enforce something "on the blockchain" in real life. Hence, the only thing a blockchain can be used for is an abstract token that does not have an equivalent in the real life, and thus can be used to represent anything - not just a house or an artwork or a chicken - but all of these at the same time and yet it is backed by actual energy. And this is Bitcoin. Every other use of a blockchain is a scam.
