>People / companies like to have the ability to dispute the outcome of a transaction

Crypto currency doesn't stop this. You can dispute cash transactions and you can dispute crypto transactions. If I pay for something in crypto and it is not delivered, I can sue, complain, etc just as I would with a credit card. What you can't do with crypto is run to visa and have them magically reverse the charge (possibly screwing over the merchant). But dispute away my friend.

This is actually valid. You can absolutely dispute a crypto currency just like you can dispute a cash transaction.

Except that only holds true when you perform a crypto transaction in the same way as you do a cash transaction, for local services. The moment you do it for something remote, you will run into all sorts of issues.

If a merchant in my country fails to deliver on a cash/crypto transaction, the dispute process is easy.

If a merchant in another country fails to deliver on a crypto transaction (posting cash is a whole other topic that we'll avoid here), what dispute mechanism do I have? International law is a minefield.
