If I were committing, say, fraud, by sending an email from [email protected] to [email protected], with both me and the recipient being in the United States - even if the connection between the Google datacenters is physically routed through Canada, you'd have a hell of a time convincing a judge and jury that I'm committing international fraud.

The owner of the wallet is what's important, not the implementation detail. The legal system cares a great deal about intent, because it isn't interested in playing rules-lawyer with wise-asses.
