sounds like you're missing the point of crypto. it's not about the data management, I think some ETH clients use postgres internally, the blockchain as a network is about removing central coordinators and trust assumptions (including ones we take for granted in our society)

The only trust that crypto removes the need for is the trust that a transaction will be recorded. You still need to trust that the person on the other side of the transaction will uphold their end of your bargain, which is literally the only thing that actually matters in any transaction.

When I swipe my credit card at the grocery store, I'm not worried about whether or not it will show up on my bank statement. Switching that transaction to crypto solves nothing, it gives me no additional assurances to whether the food I just bought is poisonous, whether somebody was watching over my shoulder for my pin, whether a delivery for something out of stock that I ordered will arrive, or anything else.

In fact, using crypto would make me less confident about those things because, since crypto transactions are eternally immutable, I can't get my money back if they screw me.

Being able to trust the fact that a transaction happened is not a useful innovation.
