Dr. Casaubon,

I hope you see that your definition as you state it doesn't clarify
things. Of which primes is 1 the product? Either your statement of the
fundamental theorem of arithmetic is broken, or your definition of
primes is broken. Either one needs exceptions to work. Either the
exceptions have to be made in the "fundamental theorem" or in your
definition of "prime." (And maybe your definition of "number". I
wonder about 0 and 1.5 and 2+3i.)
