just because you have a free market, does not mean that you have the skills to build a nuclear bomb
Not bomb because bomb has limited radius . Plutonium can be dispersed over entire planet thanks to jet streams.
We live on single interconnected world, someone else's freedom is interfering with your own even if you dont see it.
"6 billion other people will have the freedom to come and stop you by any means they see fit."
There you go , your first regulation.
"You cant buil nuclear plants full of obsolete fuel type based on plutonium".
it's not a regulation, it's a self-defense against what i perceive as your violence towards me.
you are free to try to build it, i am free to try to stop you, you are free to try to stop me from stopping you, etc, etc.
