> why does PayPal know who it's being sent to? They just need to know you and the webshop, don't they? Who the webshop sends it to is between you and the webshop.

No, it's not, because the buyer has chosen to use PayPal's services for protection, and in order for the merchant to fulfill their end of the deal and also receive PayPal's protection (against chargebacks, disputes, etc) the merchant is required to ship to the address on the order (which PayPal has a record of for verification).

If you offer PayPal as a checkout option, you are required to follow their rules for fulfillment, otherwise you risk losing a PayPal dispute if filed later on.
