Always the techno-anarchist - or ironically, the techno-fascist - dream: Technology is somehow inevitable. But somehow we have prescription controls on drugs, many materials and tools are illegal, nuclear weapons are limited to a few countries.

As a society, we have power if we want to use it. It's never perfect, but it can be very effective. Saying it's impossible is just a means - intentionally or not - of preventing people from using that power.
