There is no risk to the seller giving PayPal. The buyer has all the risk sending the BTC.
I am buying BTC with Paypal. The other party is selling BTC and receiving USD with Paypal. The seller has to send the BTC to me (actually to a shared Multisig address). I'm Sorry if I was unclear at some point.
Exactly, way too risky to send you BTC for PayPal, no matter how you try and justify it.
