Well for starters you restrict the premium the seller can offer for non privacy preserving payment options. If you want payment via SEPA then max 2% premium. Fuck off. But if you want to offer F2F/gift cards then you can set 10% premium. You need to find ways to incentivise privacy and educate.

Also the interface is not helpful or supportive. Get AI to write user stories/experiences to help you improve the UX/UI.
