For starters, the premise of the predictor is just logically impossible on its face. Set up an Arduino that checks the LED at 3:00:00 PM and pushes the button at 3:00:01 PM only if the LED was off.
You just can’t/don’t set up such an Arduino.
The laws of physics are full of mind-bending paradoxes in the real world, but they have no effect on the average person’s state of mind.
I think the point is that the predictor-boxes make the philosophical point very obvious.
I think this section is addressed best by https://intelligence.org/2017/04/07/decisions-are-for-making-bad-outcomes-inconsistent/. Your reasoning about it not providing any benefits to you “at this point” is basically assuming CDT and you could apply the same line of argumentation to Newcomb’s paradox to argue for twoboxing.
This is effectively denying the possibility of the predictors, in general.
