I think the concept of doing something wacky and bizarre is actually triggered by existential dread regarding free will.

It's deterministic for a human brain to think "Oh no, I have no free will? But maybe I can prove it somehow. I know, I will do something unexpected."

But the very conclusion that you should do something wacky and unexpected was caused by thinking about free will, which was caused by another event.

Cause and effect leads to determinism, and this determinism does not exist as a separate part of the universe, but exists the same way time does.

It's just the way it is.

It is not something you should be worried about, in my opinion. It's more wise to just focus on reality as it is, and not mourn over unchangeable aspects of reality and the universe. Best to accept it with courage, and move on.
