Considering the construction of the reals by Dedekind cuts, you'll notice there are no rationals between $0.9999 \cdots$ and $1$ , and thus they're the same number.

just because there is an asymptote doesn't mean the graph can't cross it (when x and y are small)

the asymptote only tells you things about when x or y are big

Note that decimal expressions can be equivalently defined without reference to the reals, provided the limit exists in the rationals. No need to even invoke dedekind cuts.
