"Ethical and Religious Directives for Catholic Health Care Services"

    "A person has a moral obligation to use ordinary or proportionate means of preserving his or her life.  Proportionate means are those that in the judgment of the patient offer a reasonable hope of benefit and do not entail an excessive burden or impose excessive expense on the family or the community."
   Who writes this stuff?  So a billionaire in mortal physical distress would not have to worry about imposing an EXCESSIVE EXPENSE  on family or community, but the rest of us should take that into consideration, before, say, consuming an inordinate amount of antibiotics.  And who would "the community" be?  Since this was written before the GoFundMe sites, the community would most likely refer to the insurance companies or Medicare.
    I suspect the highly touted Advance Directives and Living Wills, etc. make little or no difference in the long run, except maybe for your choice of donating your body parts. The issuing of such may serve as further justification for the decision-makers.  Legal justification, that is; moral justification has no place in pragmatic statements.
        It's simplistic to define terminology:  if you need to explain what the subjective word "proportionate" means, just use other equally subjective words to define it.  Who can separate the concept of "hope of benefit"  from "reasonable hope of benefit" or determine what amount of expense is "excessive expense"?
   I see that the "judgment of the patient" is the deciding factor.  But then, at this time,  isn't someone else in charge of determining the patient's ability to make a rational judgment?
