Well our issues are more about things like sending someone a letter, proving they got it and that the person receiving it is the person we wanted to send it to. Even with a certified letter none of those features are actually possible with the current USPS, at least not in any real meaningful way. And don't even get me started on their use of received receipts in email.

But like you said, it's all about screwing the system and I'm sure a judge would not understand any of these concepts regardless of how simple someone would make them.
