Debate: intellectual property in a AC land

[[censored]]

this debate is between mmbtone and will magic. please refrain from posting in this thread unless you are mmbtone or will magic.

mmbtone:

I believe that a lack of IP protection would be harmful to the economy. I feel any system that allows this to happen, whether AC or not, would have fewer innovations and therefore progress slower.

will magic:

i largely agree that copyright/patents will be very difficult to enforce in an AC society, but I don't think that this is something uniquely bad about AC, because

a) copyright law and intellectual property is already nearly impossible to enforce in the status quo, and enforcement will only get more and more difficult
b) the concept of intellectual property is ridiculous on face because property rights are meant to deal with scarce resources, and ideas are not scarce
c) the copyright/patent model phasing out doesn't mean the end of innovation, nor does it mean the end of artists creating media, and finally
d) you can still sue someone for explicitly violating a contract in AC.


I will start a thread for discussion for non participants
