[1, n]. My proof applies all intervals.

It does not. It applies to every single finite „interval”,

What element is not covered by all intervals that I use?

but not to the whole N.

You do not cover N, only finite parts.

What do I miss to cover?

Inf.many numbers for every n.

But Cantor using every n does not miss to cover anything?
 > N is infinite.
Every element is the last element of a FISON [1, n]. ℕ is the set of all FISONs. I use all FISONs. ∀n ∈ ℕ: f([1, n]) =< 1/10.
Ever heard of the effect of the universal quantifier?
