The question is whether a universal termination analyser can be
constructed, and the answer is that it can't.
 Aren't you kind of putting the cart before the horse with such an
assertion?
No, no more than I would be by asserting that the square root of 2 is irrational or that the sum of the squares of the two shorter sides of a right triangle equals the square of the hypotenuse.
A proof is a proof is a proof.

Maybe the prior art you are basing that assertion on is wrong?
Nobody is stopping you from trying to demonstrate this, either by writing such a program (as Mr Olcott has tried to do) or by proving that Alan Turing's proof is wrong.
Good luck with that.
