Can you spell out how that would go a bit more explicitly? The violinist argument is supposed to show that nobody gets to use a particular individual as a life support system without their consent, not that we don't owe some degree of care to one another. I'm not saying there's not a way to make a (bad) analogous argument about people with disabilities, but I'm not familiar with it and can't quite see how it would go. If you've got time to spell it out, I'd appreciate it!
