Proof: If infinity is actual, then all elements of the set of unit

What does it mean for an element of a set to not exist?
The set can be extended this element - like Hilbert's Hotel, when every
guest multiplies his room number with 10^10^10000.
Ah, but then the element does exist after all, but also somehow wasn't
an element of the set.
