The proof that all unit fractions can be defined
is to define them
as reciprocals of positive countable.to.from.0 numbers.

That describes all of them and only them.
No, you falsely assume that all natnumbers can be defined.
Huh? Confusing to me. Humm... Are you trying to suggest that a natural number can _not_ be a natural number?
Try to understand the function NUF(x) = Number of Unit Fractions between 0 and x, which starts with 0 at 0 or less and after NUF(x') = 1 cannot change to 2 without pausing for an interval consisting of uncountably many real points. The reason is this: ∀n ∈ ℕ: 1/n - 1/(n+1) > 0.And isn't defined, since there is no finite number x, such that NUF(x) has the value of 1.
