I dont agree with the argument that says "you can never stop it completely so you should not try".
Laws are not made on that basis. They never have been.
Murder still exists, but you will face significant loss of liberty or death in any country in the world if you are convicted.
This also applies to those who create content and want to control where and when it is distributed. Things will change. Legislation will catch up with technology. It always has - governments like to be in control.
Just because it has not happened yet does not mean it will. Governments can control whatever they decide is important enough to apply their will to.
The US govt did not like online casinos, so they stopped 99.9% of the population from using them. The UK govt is cajoling ISPs to control content in the name of child protection. It does not take a genius to work out where content control can lead.
Govt licenses to get your URL through the censors anyone ?
