By this logic you'd be fine if we gave every person on earth a nuclear bomb? It doesn't take a genius to understand that various pieces of technology might either change the incentive structure of society in such a way as to produce more of certain behaviors and less of others or might enable the assholes you refer to to do more harm than they used to do and in either case undesirable outcomes might increase. Unless you believe that the common good doesn't exist or that human's don't have any business trying to construct their society in such a way as to seek some form of it, you have to take the social effects of technology into account when making policy. Just asserting that all things ultimately come down to individual decisions is really weird. Like even if you believe it in some libertarian free market fantasy framework, the vast majority of people think differently and your comment provides no justification whatsoever for why "ultimately people are responsible" is a useful way to think about these problems.
