Well, here’s the thing. Once the knowledge is out, they can be made by anyone, or the tech will accomodate that path, like with 3D printing.
No way of putting the genie back in the bottle, and I’ve decided it’s time for an open bottle. Would be nice if we could ride the genie to some profit, though.
And no worries, the knowledge is already distributed.

Yes, it’s just a matter of time. The Chinese invented gunpowder, and tried to keep it to themselves. How’d that work out?
Corollary: nuclear weapons. They heve existed for < 70 years. During that interval they have been used twice. How long will that degree of control last? Be prepared in the future for “routine” use of nuclear weapons, however long that takes and whatever “routine” comes to mean.
Finally, the technology certainly exists to build a cruise missile in your garage. Ref http://www.interestingprojects.com/cruisemissile/
