Only the per-transaction costs are relevant. Just like VAT, you don’t include that you had to pay a VAT registration fee and accounting costs of X per year to process it. Agreed that it does become complicated when you have multi-tiered fee structures like that though.... Also the fact processors charge different amount to process payments from different countries. It definitely needs some thought - but the current state of things is not an ideal place (users incentivised to use expensive and inefficient payment solutions while private corporations siphon off large amounts of money from the economy just for the privilege of being able to move money around).
