If you seriously believed in that risk, you'd be calling for the regulation of computation at the same level as nuclear weapons, including destabilizing any country that pursues homegrown fab technology. If your proposal is:

- let our former employees review all of your work at your expense

- anoint us as the arbiters of what everyone else is allowed to do

- ban open research

Then you are not taking any of the examples your providing seriously. Otherwise you're essentially saying, to prevent people from making nukes at home, we should heavily restrict physics education and research instead of limiting access to uranium.
