I disagree. Medical Power of attorney is respected everywhere. Please cite a case where it has not been. ( Assumption is that your in the US )

I am not gay and have not run into this personally. However I have
friends who are, and have. I'll ask around.

I =have= had the experience where certain powers of attorney which I
held (non-medical) were not respected, because the paperwork got
misplaced (at least that was the excuse). In the power-of-attorney
cases with which I am familiar, it can get sticky, and that's the last
thing you need if faced with a bigoted administrator, a dying loved one,
and other logistical problems.

And in any case, this would only cover medical issues. There are a host
of other areas (such as real estate held between spouses).
