Some people say that it is fundamental because it establishes the importance of primes as the building blocks of positive integers, but I could just as easily 'build up' the positive integers just by simply iterating +1's starting from 0.

Multiplication is certainly not more "fundamental" than addition, but building up the natural numbers by adding 1's is apparently not difficult enough to call it a theorem. It may be how the natural numbers are defined. Multiplication and addition are the fundamental operations that are used to define the other operations.
