If tomorrow all the international drug peddlers, arms dealers, human traffickers, bonsai kitten merchants decided to trade solely on the internet, could the US or any other government actually make the internet itself illegal? Instead of cracking down on illegal businesses, could a government actually outlaw the process of hosting websites on servers or browsing the internet?
You imply the government is not related to these crimes. But often governments are corrupted and have interests in illegal things...
