Nobody chooses to be born. Does that mean that there are no moral obligations that arise by virtue of one’s existence as a human? Can obligations only arise from voluntary choice?

“Choice” is not the be-all end-all of morality (or, really, even particularly important). The obligation for parents to care for their children and vice versa arises from the nature of people and the nature of the relationship. Parents have an obligation to care for children even when they didn’t choose to have children. Conversely, children have an obligation to care for parents even though they didn’t choose to be born.

People who didn't choose to have children are not called parents.

You've offered nothing to support this supposed (but not really) symmetry. This seems like back-rationalization of some cultural norm or tradition (especially when coupled with your anti-individualism swipes in the other comment).

Perhaps your beliefs are not as preordained as you may believe.

This isn't and one off believe system. It's strongly prevalent in most non western countries and was prevalent in western countries for a long time before now. We're the outlier not him.
