The next iteration would be to collect child support from deadbeat or recalcitrant sperm donors. Which, if I’m not mistaken has already been tried in a court of law, and I am unsure of the legal outcome of that decision. But I do know that the decision to become either an Anonymous or Non-Anonymous sperm donor is final and irrevocable. If you were undergoing in-vitro you had to sign paperwork that stated sperm would be available for x amount of years and that you agree that the Clinic could dispense your sperm without your notification, and that no claims could be made against the recipient.
But hey, it appears laws or contracts are seemingly made to be broken, disregarded, litigated, or rewritten.
