I can speak objectively about this because I watch the network every day. Tens of thousands of listings on the network and the vast overwhelming majority are legal and moral. People use it because it's cheaper and more private than alternatives. There are some illegal drugs on the network. Thus far I haven't seen any evidence of the other stuff you've claimed. Perhaps it's human nature that people will eventually abuse the technology in that way, but it doesn't mean the technology isn't valuable, and it doesn't mean that the benefits don't outweigh the costs. This is obviously an age-old debate about new technology, but if we had the mindset that any technology that can be used for evil shouldn't be allowed to exist then we wouldn't have TCP/IP and HTTP and SMS and SMTP, etc.
