There is never any forced obligation. The point is that every parent should treat their children well enough that they love and honor their parents so much that they want to do all they can to help when the parents need help. Even the worst psychopath parent has a bit of incentive to treat their children well if they knew that this was the difference between having some comfort in their old age or being forgotten in some dreadful government facility being half taken care of by some stranger who doesn't give a fuck if they lie in a pool of their feces for hours.
