Note, "inifinite" isn't a Natural Number, or a Real Number, so NO
segement, specified by values, can have an "infinte endsegment".
You seem to have a definitional problem.
Of course, since you logic says that infinite sets act just like finite
seqments, and thus no set is actually infinite, as well as that 0 is
equal to 1 since they are both limits going to the same target, such a
confusion is only natural.
