There's nothing "conspiratorial" about assuming fundamental principles of human behavior, even baked into neoclassical economics (which you might also subscribe to) and any realist political theory. Not only that but real conspiracies at this level happen almost constantly[1], John Bolton just admitted being involved in some yesterday on CNN[2]. Don't be dismissive and condescending, especially when it's quite possible you're wrong.
