In theory "yes", but who do we both know that we can trust?
I am willing to trust Roger Ver, but I am not sure he is still doing escrow or how much he would charge.
PayPal is actually a form of escrow and they always side with buyers on chargeback claims. Even with dual proof of delivery (blockchain tx and a mail delivery), they will still side with the buyer. I have to send them a demand letter & file a small claims case to get them to be honest and release my money whenever I have a dispute.
Not only that but you are also risking that the buyer is using stolen PayPal funds
