We've built economic and social systems that allow most people to die of what we used to call "old age" and now name as specific diseases that typically manifest in old age [rather than starvation, expousure, or predation].
That people have to contribute in some way to enjoy the fruits of all that aggregate labor doesn't seem so unreasonable to me. All the people required to do all the back-breaking work of farming, transporting, building, cleaning, purifying, and cooking aren't going to do that labor while you enjoy life doing nothing constructive that helps them via some chain of events/transactions.
