Theory is probabilistic, nature isn't.

Of course it is. What you are suggesting is classical determinism.

I don't know dog, that is a pretty bold statement given everything we can presently firmly say about the universe.

Like we can imagine some kind of purely deterministic thing going on but when the rubber meets the road the best ways of working stuff out seem to very strongly imply some fundamental indeterminism. No one likes it, but thats the way it is.

When the rubber meets the road the best ways of working stuff out is to shut up and calculate, you don't figure out anything by assuming unobservable fundamental indeterminism.

No one assume it.

Nature doesn't obey your opinions.

That's an argument against solipsism at best, not much else.
