The only real “new” issue that would come out of this is the hypothetical problem of stealing DNA from someone else to create a gamete. Granted, this technology is still very much in its infancy and, while the promise implied here is that you can create the gamete from any cell, in practicality, it may require a good quality sample of a specific kind of cell to reliably make this happen.
As someone who is active in the Donor Conceived Community, being a product of donor sperm, this process would remove a lot of trauma from the offspring of these arrangements. A big problem is that a lot of offspring did not receive the benefit from genetic mirroring which causes some issues when the child is not informed at the earliest age.
Some of these problems stemming from this trauma include developing trust issues, feeling of not belonging, and even a poor ability to recognize faces later in life. There’s also the problem with large sibling groups even to this very day due to fragmented rules and sparse regulations.
Growing up with genetic family does prevent the bulk, if not all, of complaints fielded by offspring such as myself. This is it something parents, both perspective and current, never want to hear because it’s upsetting, uncomfortable, and it’s a threat to their self. If they accept this, they accept that no matter what they do, they may never be good enough if using an anonymous gamete donor. While this is not true if you take a child-centered approach, the conversation has usually ceased by now.
Newborn babies are not a blank canvas for painting upon, nor do they exist to please and serve their parents. The DNA they are born with links them back to their biological parents and absence of one or both without that knowledge is trauma, unfortunately.
The pedants are going to catastrophize with wild hypotheticals from their armchairs, but I know this can be transformative for many who seek gamete donation and greatly beneficial to their offspring who are born with this technology.
