True, but then you need someone to manage the escrow payouts. And doing that requires a trusted third party to do work, and so they charge fees to finance that. So, basically reinventing a credit card company, but on a blockchain.
And these services do exist and are in use on some tor network marketplaces.

I don't expect fees to be much lower for a third party human-in-the-loop escrow system. And there's nothing wrong with "re-inventing" either. I think it's critical however that you can have strong censorship resistance and opportunity for innovation. So personally I'm more interested in the unknown unknowns, rather than recreating exactly the same.
