It seems to me doctors are capable of determining what's medically necessary, yes?
While generally capable, some situations aren't clear how to handle.
The decision how to proceed must balance the risk of being wrong,
reversibility in case the choice later turns out to be wrong, delaying
the decision until the affected person can choose, necessity of
immediate action, & who knows what other options are compelling.
I can see that sometimes, a course of action shouldn't
be up to a single doctor or even the parents.
But up to whom?
A committee...how chosen?
With what authority?
I don't have that answer, except to say it
should not be
the fundamentalist rabble found in legislatures.
