I would replace "orchestrate" with "influence". It's obvious it can be influenced negatively, to make the situation worse in context of this discussion -- otherwise the concept of bearing responsibility to influence it positively, which you acknowledge, would make no sense.
As for "force of nature", that just sounds like what someone living under monarchy might say about monarchy, etc. Yes, trading things is very old and very useful, but from that doesn't follow that the whole package including "obfuscating ethical implications" is a "force of nature" (which to me doesn't really read differently than "the will of God" btw)

We're first and foremost talking about personal responsibility. To speak about "the system" we should "improve" while kinda skipping about that is like talking about a beach while ignoring the concept of a grain of sand. The system is the people, the beliefs they have about the world, the other people, and so on. If you take away the people, there is no system. With different people, there is a different system.
Yes, I cannot easily just change the behavior of others. However, I can change mine, and there are a lot of things I declined to do because I value being able to look at myself in the mirror more than temporary material profit. What force of nature? I only saw and see a bunch of mediocre, insecure people who failed to drag me into their games.
When a group of hooligans steals money from a beggar just to be cruel I may not be able or dare to do anything about it. But it's very easy for me to refrain from stealing from a beggar. It's actually way easier for me to refrain from it than to do it. Other people developed differently, probably had different childhoods and so on -- but we still live in the same "system", and "just" behave very differently in it. That matters.
