How will I get insurance or coverage against fraud in a permissionless system -- who will be my intermediary?
There's no reason why you can't have those same systems on top of Bitcoin. For some applications they can be safer, like openbazaar vs ebay.

I don't want to learn "How To Choose a Good Moderator." I'd like to have someone with deep pockets that I can sue for damages if they don't keep their guarantees, like Visa.
Ebay or Visa could easily be a moderators on the platform.
And they would be safer than they currently are, currently they can theoretically run away with your money and your best hope is to sue them.
How do they get paid? I didn't see that in the FAQ. Presumably they take a cut from the seller? If so, I'd imagine it might be frustrating to negotiate which 3rd party you pick for what fee for each transaction.
It might not be bitcoin, but it certainly won't be Bank of America coin.
