If we completely remove the selection constraint that humans are able to reproduce, over time functionality bugs will creep into that area. If, at any point in the future, society collapses to the point where we are no longer able to build these machines, we may no longer be able to reproduce and will simply die off. Maintaining this constraint on humans seems prudent. If and when we can manipulate genetics well enough to fix the issue in the actual human organism in a way that is not fragile, then that would be fine.
