Nonsense.
1 can be counted to (obviously). If n (where n is a natural number) can be counted to, then n+1 can be counted to (obviously). Hence for each and every natural numbers n: n can be counted too. qedBut not all endsegments have an infinite intersection. All endsegments have an empty intersection. Since every endsegment can lose only one number, there must be infinitely many endsegments involved in reducing the intersection from infinite to empty. Their indices however cannot be counted to.
Just the indices involved in reducing the intersection from infinite to empty. They are dark.What one cannot be counted to?
