You say this as if it is necessarily a bad outcome. I’m not convinced that everyone’s
last choice is any worse than a minority’s first choice. (what you propose is not
possible if a majority voted for said first choice).
In most cases, STV will yield a result more reflective of the community’s overall
desires. Yes, you can cite corner cases where a potentially objectionable result
can be obtained, but they are actually somewhat difficult to contrive.
As you note, there are alternative RCV options that lack this particular anomaly,
but they present others.
Overall, I’m fine with most of the RCV options available, but generally prefer STV
as its mechanics have been well studied and its results have proven to generally
provide a superior result where it has been implemented.
This is not to say that unlikely and pathological elections do not occur. (2016
U.S. Federal comes to mind). The sad part there is that to a large extent, that
was the result of the pro-slavery provisions in the constitution doing almost
exactly what they were intended to do.
