I apologize if I gave that impression, but I try sometimes to be not too much long in the mails, and being short can have given that impression. Sorry. My point was just that there is a sense where natural numbers are not enough in math, and that is why mathematicians have extended the set N. N, then Z, then Q, then R, then the complex numbers, then the quaternions, octonions, etc. But, once we assume comp, N is "ontologically" enough, all other sort of numbers do necessarily appear as unavoidable epistemological constructions, if only to understand the (additive-multiplicative) behavior of the natural numbers, a bit like Riemann use complex numbers to provide information on the prime (natural) numbers. Without digging a bit more on the technical issue, I can hardly say more than my usual: there is only natural number, together with the additive and multiplicative law. This, assuming comp, already defines a "matrix" of number's dreams, and those cannot avoid the internal phenomenological appearance of richer structures, like the "other" numbers, and indeed like the whole physical appearances. Does this help you a little bit?
