Regulation, for instance of BSL-X labs is basically a comical witch hunt executed recreationally by amazingly un-knowledgeable people. The biggest risk of biotech against humans is: governments making weapons systems.
Nothing can possibly touch the scope and resources that always begin: "We have no choice but to spend and do, the enemy is already doing X, we need to defend against it". Yet inevitably, to figure out a technology means to learn to use it. The definition of a defensive system is based on which side of the things you are standing, not what it does.
The difference is between a teenager ( nothing personal ), who makes a big bottle rocket and starts a grass fire ... and a H-Bomb.
Sorry. 5000 H-Bombs.
"Regulation" will work as well as intervention of recreational drugs over borders, that is, be entirely ineffective selectively, only stopping what doesn't matter.
Go ahead and make a fat document. Seeking answers to problems that are insolvable is a good path to income and pseudo-authority...
