Can't argue that, but most non-US or Canada buyers aren't Confirmed anyway.
I really think it's a bad idea to ship to other than a PayPal authorized address. If the buyer wants to add a US address and deal with their credit card company on the shipping issue that they authorized, I think that has a better chance than a PayPal charge-back.
I also think it makes a good play with PayPal to have done everything correct and the buyer having Insurance as the clincher.

Keep the cheese. I just want out of the trap.
