This assumes the philosophy of intellectual property is compatible with the world of cryptocurrency with a focus on anonymity.
Pure anarchy tends not to work well.
Copycoins would have a choice:
1. Licence DarkSend, benefit from the hard work being done for them and existing market recognition.
2. Use DarkSend unlicenced, good luck getting any serious investment due to the blatant illegality of it
3. Come up with something themselves, ie hard work
Works just fine actually. You going to have the state enforce this IP model? I don't think so.
Give me some examples of functional anarchistic societies that involve more than three hippies living in a commune...
I'm no fan of "the state", but if we can play the system to our advantage at close to zero cost then why not?
In your anarchistic utopia the only currencies that matter will be ammo, water, food, medicine... same as it ever was.
It's the pockets of Anarchy in every society that keeps it moving, nothing could be done without it.... but there's plenty of places you can go on the internet and learn about how wrong you are there. The point is, crypto is the last place intellectual property will be respected... because it only exists in the minds of statists.
