Then the axiom of _Infinity_ makes absolutely no sense, because it says

The axiom of infinity says nothing about applying the successor
function an infinite number of times. It just says there's a set
closed under the successor function.
Infinite compositions of functions are routinely employed with
fractals.
Sure. And as said in that context what is meant is explained by limits
of convergent series of functions and so on.
