"As long are you are not a criminal, ownership and liquidity are not huge pain, what is the real, tangible benefit of decentralized banking?"
Capital formation for any common purpose without trusting 3rd parties. As an example -> there are some NFT vault DAOs where strangers pool together to purchase NFTs that are too costly. People Vote on proposals regarding which NFT to acquire and when.
This value of this kind of thing depends on NFTs having value, which I would dispute. As soon as a DAO tries to buy anything in meatspace (a house, a painting, a book), you're back to an oracle problem where someone has to be trusted with the custody or upkeep of the physical item and no amount of DAO votes can force them to do something they don't want to do.
It's difficult because blockchains have not yet scaled the infra yet. The amount of data that we can currently put on most decentralised chains is very less.
This will improve though and allow us to put a decent amount of data on the blockchain.
Why is it so difficult to find utility with this "tech"?

I am not convinced that monetary transactions should be above the Law, and for them to be lawful they have to be centrally regulated in some ways.
