In actual infinity, this is not avoidable.
We note: At least two lines belong to the set that contains all
numbers. We call these lines necessary lines.
So the set of necessary lines is not empty.

Why then should two lines be necessary?
One being the substitute in case the other falls ill?

If there is not one necessary line, then there are two or more
Proof: If you remove all lines from the list, then there remains no
line and no number.

So you believe that there can remain all numbers in the list after
removing all lines? That is a remarkable claim. I would not accept it
Note in actual infinity it makes sense to talk about all lines and to
remove all lines.
