the question is how do you define a function. You seem to want it to mean the a function takes a value and by some proccess it manufactures a new value. If you can formalize it further you may have an interesting concept. The usual definition of a function is not like that. A function is just a relation satisfying some relation. Under this definition there is no problem with what was proposed.

you are right, but it is an effective way to define a function.
