Regarding charge backs, why can validation node not simply make a transaction back from the fraudulent vendor to the consumer.

Obviously, there would need to be adequate proof that the nodes then review, but once that is given, what's the problem.

Furthermore, the fraudulent vendor would be investigated for fraud and facing a fine or jailtime.

This could be a dapp on the blockchain.

I don't see why this can't be done by a team of trained lawyers and judges that review these fraudulent transactions.
