I'm a long term customer of Steam _and_ work in the payments industry. In the _easiest_ Steam payment there are 7 different parties extending or receiving credit from each other. Most of those counter parties have no relationship with each other at all (I certainly don't maintain close ties with the game publishers bank), do you?
The rules that are being invoked around porn exist to protect different parts of that chain, from each other.
The argument about Steams ability to revoke the good in question doesn't help with that. What it does is provide an alternate path if Steam wanted to extricate themselves from that chain of 7 counterparties. Steam could stop being involved with all those other players and become a payment network unto themselves. They could demand ach (or cash in the mail as the parent suggests). Give the game with the understanding they would rapidly revoke it for bad customers, and limit their exposure to the publisher by giving them very delayed payment terms. Of course, then the customer is taking on more risk and losing choice and Steam has to account for that in their sales numbers.
