If it's backed by gold, what about the certificate and the storage (and the cost to store in the vault). It's going to make a centralized currency, ...again... it doesn't look something easy to create. Also just to remind you, the us dollar was backed by gold until 30 or 40 years ago
All the conjectures here are just conjectures given there is nothing to verify them. It's just to express the discussion for the story. What's the property like? What is the value of money? All of them, with the effort of the future, can prove them. In fact, it is still necessary to use gold as a decorative item, while currency (usd) for economic circulation, and electronic money for the technological age. Each asset has its own features and needs more time to make decisions for them. I think so.
This is just what we like to do. Speculate, make conjectures, and wonder about strange things that we have no idea about. Sometimes they may come true, if we can make the connections ahead of time.
The wonder of crypto lies in it's immature nature. It is still a naive asset that is trying to establish itself in the market and no one really knows how to treat it. There are still arguments going on whether it's a currency or asset or whatever. This means that it still hasn't settled, and it has great potential because of that.
