Those who try to forbid the detailed analysis are dishonest swindlers 
and tricksters and not worth to participate in scientific discussion.

Therefore the sequence of intersections loses all content.
E(1), E(1)∩E(2), E(1)∩E(2)∩E(3), ... --> { }

The end is reached when all content has gone because more cannot go. 
Then the intersection of endsegments which was not empty before has 
become empty. This cannot happen other than by the law
∀k ∈ ℕ : ∩{E(1), E(2), ..., E(k+1)} = ∩{E(1), E(2), ..., E(k)} \ {k}

That is not a property of infinity but illogical nonsense.
