> Fraud and Risk come in many forms, and these providers, even with their UX innovations, sit on top of those same rails to reduce fraud. Without those rails, buyers can’t trust sellers and sellers can’t trust buyers. In my opinion, you need to find a way to solve that problem before you can eliminate the fees being captured by these providers.

And failing the elimination of those issues there will always be some fees. New vendors can pop in and push the fee structure down if they can run a more efficient operation.
