A better example would be: I create a political party, and expect that if it win, it will call a street at my name and pay me a lot. The difference with service is that if I will not start this project, it will never exist at all. I may instead create some different project and get different benefits from it. So from my side it is a trade with an entity which is only possible at the moment of the trade.
