I don't see how it is anything other than inevitable. Religions, governments, other organizations/entities have a lot of reasons and not all will be prevented from doing so.

The essential problem of modification isn't who is tailoring people, but that anyone at all is tailoring people. It legitimizes the notion that human beings can be made subject to the wills and desires of others in the manner of an instrument. It's the same moral stance that enabled chattel slavery, but worse. Much worse.

The idea is just reheated science fiction, but the underlying hubris, and resulting moral blindness, is even older.

>"but that anyone at all is tailoring people"

From what I know "untailored" people do not develop into anything meaningful on their own.
