Either there is a complete and fixed set ℕ with a fixed number |ℕ| of elements.
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.

 The number of nines is not a number.

The set of natural indices is a set.
Shifting it to the left shifts every index and every indexed nine to the left.
