Likewise, I was wondering. If I know I'm not a money pump, and every trade I make is beneficial to me, can I model the rest of the market as a single big agent that is a money pump?

Can I reverse this process to build a model of the world as an agent, and then find a sequence of beneficial trades?

For sure you can. This is just what traveling merchants did/do. You buy X from people with Y>X and sell it to people with X>Y while at the same time buying Y from the second group and selling it back to the first. Of course, you're not actually hurting anyone, indeed, everyone in this scenario benefits.
