I wouldn't call it nihilism. Nihilism says existence is without objective meaning, purpose, or intrinsic value. I say the opposite.
To each human being, existence has infinite value, to the extent that nothing else matters.
Of course, that's an extreme statement, and there might be circumstances where even with such beliefs, one decides that something else is of more value (or, conversely, that life loses its value if a life-ending action is not taken). But the point is that you start from a standpoint of infinite value, which makes any declaration that "I don't want people to spend tens of thousands of dollars to keep me alive" completely obscene, a bit like if someone said they don't want to spend $1 to stop you from going blind.
