I agree with this statement, but it's pretty academic. At this stage of the game (metastatic capitalism), people aren't generally allowed to have interests that don't serve capital. Like, there may be some philosophical "best self interest" which is beyond the capture of capital markets, but it's not part of our culture.
Besides, look at context. We are talking about what a company does and the agents of the company. Of course it all collapses to serving capital. I read GP as "why would company take short money over long?"
