did you see what they did in the netherlands? they threw a guy in jail because the code he wrote and deployed to a decentralized network "could not be stoped" and made him responsible for the criminal actions commited with that code.
that is like someone is drowning a guy in my pond, but now it is my fault for deploying an unstoppable pond. it makes no sense, and has to be fought tooth and nail.
and before you say "yeah but he made a tool that is useful for criminals"...
Everything that is remotely useful is also useful for criminals
