Exactly! In my opinion, one of the implications of this fact is that you cannot make trades like "I am sacrificing x now, so you will buy me a house/whatever when I am older" with your unborn children.
How about "I am sacrificing x now, in the hopes that you will buy me a house/whatever when I am older"
Or what about "Sorry, kid, I technically provided you with food, water, and shelter. You can walk to soccer practice, as I have no legal obligations in this matter"
For some people, the answer may rest on whether the child is younger or older than 18.
That said, I don't think people from collectivist and individualist cultures can ever agree on what the obligations a child has - if any - to their parents and extended family.
