Hurdles in Implementing Internet Censorship for Child Protection

In my opinion, the challenge of preventing the transmission of offensive material across the internet to minors must be considered less from an ideological standpoint and more from a practical standpoint. Many civil libertarian groups oppose restrictions and regulations because they interfere with the freedom of the internet and could be co-opted to prevent access by adults to legitimate material. Parent groups favor restrictions because the price of children having access to such material is too high. However, to both these parent groups, I would respond: how?

The problem of censoring offensive material from the internet is not just an ideological question, but a practical one. The internet is not under any one government's jurisdiction, and thus, the United States has no power to restrict the transmission of pornographic material; if the United States were to institute such laws, such material would be equally accessible, but would be hosted on foreign servers and databases rather than domestic ones. Practically, regulations on such transmission would be completely powerless. We can see this with a concrete example of piracy: piracy is already illegal, yet governments and companies have little ability to combat the pirates. In that case, there is a profit motive of billions of dollars, and yet there is still not an effective solution; what will the solution be when the problem has no profit motive?
