Proof (by induction): 1 is "countable" (at least in my book). If n is "countable", then n+1 is "countable" too (again, at least in my book). Hence all natural numbers are "countable".

Wrong. All numbers counted this way belong to a finite set*) upon which the infinite set**) of uncountable numbers is following.
∀n ∈ ℕ_contable: |ℕ \ {1, 2, 3, ..., n}| = ℵo
