Assuming that you don't have health issues that would make your hemoglobin
less saturated with oxygen at altitude than normal, and assuming that you
don't intend to challenge FARs pertaining to the use of oxygen, what do
you see as the value of carrying an oximeter?

I can't speak for the original poster. However...

An oximeter provides useful information, even if you don't have specific
health issues, and aren't intending "to challenge FARs pertaining to the use
of oxygen" (whatever that means).

The FARs require the use of oxygen. They don't stipulate how much to use.
So, you can either rely on the calibration of your oxygen equipment, or you
can get some actual feedback on whether you are getting enough oxygen. The
latter (via an oximeter) may either show you that your own physiology
requires more O2 than normal or (more likely) that you can use less oxygen
than the likely conservative flow provided by the O2 equipment.

Beyond that very useful information, it also provides feedback regarding the
performance of your oxygen supply. It's one extra check on whether you are
getting enough oxygen, to help ensure that something doesn't go wrong
without the pilot knowing about it.

Hope that helps.
