“The EPR claim of an "all values" spread in the coordinate depends on an idealized absolute and exact measurement of p with \Delta p\ = 0. Since this is physically impossible, the claim of "no physical reality" can be negated.”

Context: Many people would claim that the boundary conditions are not part of physics but belong to metaphysics or religion. They would claim that nature had complete freedom to start the universe off any way it wanted. That may be so, but it could also have made it evolve in a completely arbitrary and random manner. Yet all the evidence is that it evolves in a regular way according to certain laws. It would therefore seem reasonable to suppose that there are also laws governing the boundary conditions.
“I'm sure a mathematician would claim that 0 and 1 are both very interesting numbers.”
