WM pretended :
The set of natural indices is a set.Either there is a complete and fixed set ℕ with a fixed number |ℕ| of elements.The number of nines is not a number.
If so, then 0.999...*10 = 9,999... where the number of nines has not changed by more than 0.
Or this is not the case.
But assuming completeness and simultaneously claiming different numbers of nines is stupid.
