Sort of, but then philosophers have certainly discussed the topic of why would there be conscious experience if it didn't serve any function. It would be cruel irony if consciousness was a vestigial appendage of the cosmos, an unempowered observer. Not a proof of anything just something to think about.

For me, the real driving idea is that what we call physics is the aggregate behavior of conscious entities making choices, rather than being this framework that consciousness can "override" or worse, something that consciousness is forced to sit and observe. That idea simplifies a lot of the mysteries for me.

I think the best argument for consciousness having an effect on the physical world is that the physical world contains a formulation of the hard problem of consciousness. If consciousness doesn't affect what words get written, then no discussion of consciousness is actually about consciousness.
