Even the meanest form of worm will try to avoid being killed.
You can negate your right to continue breathing by initiating force, fraud, or theft against another person... But that is a different argument...
“The will of the individual is what should matter here. If my last wish was to be kept alive as long as possible, no matter how incapacitated, in the hopes that some day they may find a way to fix me? Then killing me is causing me harm. Absent no such wish to DNR (do not resuscitate) being expressed, the default should always be pro-life.”
Please address the financial/economic aspects of keeping you alive as long as possible, no matter how incapacitated, in the hopes that some day they may find a way to fix you.
