Believe it or not, people of any stature and role can have terrible ideas. What you're leveraging is a very clear appeal to authority fallacy. Arguments should stand on their own merits and if you evaluate them on their merits, they fall right down.
Judges aren't experts in technology generally speaking, they're not experts in economics generally speaking and they obviously don't know much about blockchains.
I don't care if he's the King of England, the fact remains. Trustlessness is all-or-nothing. If the chain can become out of sync with the real world, and the real world trumps the chain, then you do not have anything other than a slow and annoying database. This is called the oracle problem, and it remains thoroughly unsolved.
Not to mention real estate on the blockchain is one of the absolute dumbest ideas to date. A bearer token representing ownership of your house, lol. You lose your keys and now someone else owns your house?! I can't wait for Kim Jong-Un to own half the midwest through the Lazarus group.
As of now, the only thing you can extend the guarantees of the blockchain to are things that are wholly and completely represented on-chain. That means basically just 'money.' Literally nothing else is a good fit with the model. And that's before touching on its sheer inefficiency.
But let's come at it the other way. If it has so much potential and we've invested billions and billions of dollars in it, why has every company that tried it given up on it? Why is it still the future, 15 years later? Plenty of ideas that first came to market back then are now the present like the iPhone. I think you and the Judge may be the ones missing something, no parent poster and I.
If you actually manage to take to market a better solution to a problem I have leveraging a blockchain, I will be the first to use it. Stop telling me it's the future and make it happen.
