The rule of subset proves that every proper subset has fewer elements

No such rule for infinite sets.

For all sets.

No, this is not an accepted theorem of mainstream mathematics.

No, you can number the primes.

Yes, there are only few known primes.

...you can enumerate them in the sense of a bijection to N:
there is a first prime, a second and so on for every natural,
which is infinitely many.

The rule of construction yields the number of integers |Z| = 2|N| + 1
and the number of fractions |Q| = 2|N|^2 + 1.

Those numbers are equal.

Only for cranks. In mathematics we use the limit. For every large enough
interval the even numbers are half as many as the natural numbers. This
does never change. Consequently it holds in the limit for infinite sets.

And half of infinity is still infinite.
