I make a point of banning people who demand paypal, or even ask for it.

Better ban me, message me if you want the full list of my eBay login IDs and I will gladly supply them to you so you can block them all.

When I sell I encourage PayPal.  For me, it gives my buyers confidence that if something does go wrong that they can make a claim.  I've never had a claim against me when selling.  I have many repeat buyers, some of whom offer to pay by bank deposit once they know they can trust me.  They trust me because I encourage PayPal when they first buy from me.
