The concepts of copyright and patent are very much 20th century ones.
The idea of trying to control "copies" made sense when you had to have expensive equipment to make the copies and the idea of allowing people to hold control over the new inventions made sense when you didn't have a way for everyone to communicate.
But we don't live in the 20th century anymore.
What we see now is that in the US companies try and keep copyrights alive "forever" (just look at how many years they keep extending the time frame for copyright on music) and with patents many corporations are able to just "stifle" any development of new ideas (which was supposed to be the very point of patents) which is why it has taken so long for many alternative energy technologies to even appear.
We don't need these "artifacts of the past" as we have "crowd funding" and "crowd sourcing" to get things done much more efficiently.
Let's stop supporting antiquated ideas and start pushing forward some new thinking (this is the space that Bitcoin is a big part of).
I entirely disagree. It's in the fact the opposite of what you propose. Copyright laws encourage entrepreneurs to do and create new things(inventions, ideas, and the like). Yes, Bitcoin's open source initiative is great, but you cannot expect everything in life to be open-sourced, just as you cannot expect everything in life to be decentralized(It's way too costly and some things are close to impossible to decentralize and still have a working product, such as a company or school). Alternative energy(If were talking about electricity and others being an alternative for oil as an ex), has been around for a long time, it's just that oil has such a grip and is so profitable for countries and companies, that it's hard for other alternate sources to make a big appearance as of yet.
I agree only upto the point that there are some people that abuse the copyright system, such a the guy who patented SSL(and has been sueing companies and winning for over a decade).But for most people, copyright laws is a protection for them so that their hard work doesn't get ripped of by some fool who copies them. Ending something as needed as Copyright laws would ensure utter chaos(As scammers take advantage and try to pass of other people's products as their own, without fear of being prosecuted). It would be x100 worse than the current haven scammers have with Bitcoin based services(All those ponzi schemes, exchanges stealing coins, etc).
