If you are going to go through an exchange anyway, how is BTC helping you? Both parties still need to trust coinbase or whatever and ultimately the transaction is identical to using venmo.
I can't use Venmo, thus I can't exchange anything between you and me.
Cryptocurrencies is this neutral third party that won't care about borders. Venmo could be your exchange, while mine would be something else. That's the beauty of it.
We are lucky, we have ways to handle money transfer relatively easily between US and Canada (my country) so that's not so much an issue, but that issue exist.
