Some people believe that you shouldn't be able to own anything that doesn't physically exist.
You can physically own a book, a CD or a hard drive but you can't actually own the data stored on them without interference from the state.
Patents, trademarks, copyright are all totally artificial and only have been bought about fairly recently by laws that restrict the exchange of information.
Throughout history people have been able to own material possessions and trade them freely, whether they be pieces of jewelry or cars. The only time such rights have been removed have been under communist systems and even then, for the most part, they have allowed some private ownership (the only exception I can think of is Kibbutz). These were highly artificial and consisted of many laws put in place by the community to restrict trade, ownership and essentially freedom.
There is a damn good argument for simply abolishing all forms of intellectual property and allowing free exchange of information. Many people would argue that such a policy would be socialist if not even communist and I might agree, but it certainly wouldn't restrict freedom the way Marxist states have done, on the contrary it would have the opposite effect. Imagine been able to download all the music and software you like and distribute it to your friends without worrying about fines? Wouldn't that be great?
Some would say, but fuck there wouldn't be any music, there wouldn't be any software or books. However this this bullshit since there were books and music before copyright and many pieces of software have been written that don't place any restrictions on their usage.
So how could a government abolish all IP?
It would be a lot easier than doing what the Soviets did when they abolished ownership of the means of production. Land was physically seized from farmers and industry forcefully nationalised with fuck all compensation given to anyone.
All the government would do is abolish the existing controls on information exchange, no one would be killed or have anything physically taken away from them.
Of course there would have to be limits to this policy, for the sake of security, non disclosure agreements would have to remain legal (I wouldn't want my bank freely distributing my account details to everyone) but that's about it.
Anti-competition Anti-monopoly laws could be put in place that dictate that the maximum price one should be expected to pay for information shall be no more than the cost of transferal. For example, you could sell music CDs but at no more than the cost of producing a blank CD and the same goes for books and everything else. Instead of people been taken to court publishers and record companies would sued for overcharging.
The basic idea is that no one would get paid for doing nothing. Today, if someone makes a few hit singles, they can do nothing for the rest of their life but under a no copyright system they would only get paid for live performances.
I'm not saying that such a change wouldn't have a short term negative affect on the economy. It would ruin the current, film, music and non-free software industries because it isn't compatible with their business models.
Positive changes can fuck things up in the short term, only to improve things in the long term. This happened in to Russia when the Soviet regime collapsed, the transition from a centrally planned command economy to a market economy was not an easy one, it fucked things up for about 10 years but now it's stronger than it was before.
A similar thing could happen in today's capitalist countries if IP were abolished. In the end people would still play music, write films, books and software and make a living for it, just not in the same manner as they do today.
I can't see any of this happening any time soon because large companies have too much power and countries have too much to risk for political reasons. For example if Gorden Brown's government decided to abolish all IP, the UK would be kicked out of the EU, world trade organisation and have sanctions placed up on it.
Maybe one day when people finally get sick of DRM restricting their free speech or companies and governments realise that it's no longer viable to restrict such freedoms it might actually happen.
