In cryptography either you only need 'an x', in cases that the original x does not matter, or if it does, then you can just as easily find all x of size less than large enough N and find 'the x', it is still solely restricted by time.

Laplace's demon, information loss, Landauer's principle etc. are at most tangentially related to the problem discussed

You understand that isn't the same mathematically as reversing the hash? If you farm the set of all possible x and try them to see what works you do not have an inverse function in your hands.

I'm not sure I follow, what do I have then? Could you give me an example?
