What if time paradoxes are simply allowed to exist?

Basically the title.

I would have gone back in time and killed you before you could post this question.

Or at least, one of my parallel-time doppelganers would. Knowing me I would have killed the wrong parallel you.

I don't see much that could be done about it. They are excluded from physics because no such paradox has ever been observed by physicists. That might change some day. Who knows?

Carl Jung observed something of that sort late in life. He went with a friend and saw a mural. Later he contacted the mural site, who told him that that mural hadn't existed for years. Both Jung and his friend agreed on what they had seen.

But does precognition, of the kind believed in by Jung, create a time paradox?
We already have one rule for classical mass-energy and another for quantum wave states, why not a third for pure "Platonic" information? Events in quantum-state time can appear backwards in macroscopic time (e.g. the famous entanglement experiments), might events in mental-information time not do the same? If they do, then there is no paradox, as no classical law of thermodynamics is broken.

We would have to question what we would see these paradoxes and what physical effect they would have. Like would the timelines branch or would the entire universe be put into a superposition. The grandfather paradox really boils down to where did the person who killed the grandfather come form if he is dead. A splitting timelines would say that the person killing the grandfather came form a parallel timeline where that person exists. A superposition view would just say the person came form the other state in the superposition. But what happens when the superposition collapses? Can It be collapsed? Would it immediately reform?
