You still ain't never caught a rabbit.
Dirac delta, infinitesimals, irrational numbers, transfinite ordinals, ... are legitimate not because they have been rigorously defined but because they can be used to SOLVE PROBLEMS. See, for instance, Jesper Lützen's "The Prehistory of the Theory of Distributions" http://books.google.com/books?id=pC7vAAAAMAAJ
No one has ever anywhere actually used the concept of a uniform distributions on N to solve any problem.
You can't even show how to use it to calculate the area of a triangle.
