The level of your ignorance is stunning. I just proved to you the existence of debt. I proved that the debt is an existing thing and that the numbers that quantity that thing are therefore genuine.
And your response is: "bitcoin the same". Hahaha. In a rational discussion, what you are supposed to do, is to show a thing called bitcoin. Only in that way you can prove that the numbers attached to the addresses are genuine. You are not supposed to make nonsensical claims of equivalence between an existing thing and a thing whose existence you must demonstrate.
So, can you demonstrate the existence of bitcoin? Can you show where's that revolutionary digital commodity? No, you can't. You already demonstrated that you can't. All you can do is talk nonsense and play semantics.
So, cash is the only fiat that we should care about and the digital numbers in our bank accounts mean nothing? Or the stocks that I own worth something just because we said so and we decided it worths it and now since I can't provide proof of it existing in my hands physical suddenly they worth zero as well?
I have to go out and let Elon Musk know that he is not worth 100+ billion dollars! He will be devastated! All jokes aside, bitcoin has as much value as the money in your bank account, maybe you can't hold it in your hands, but it has value, you can turn it to dollars if you like dollars so much, or any other fiat, or you can buy things with it, which is enough proof that it exists. Same as fiat.
