well, I happen to agree. Pirate - thief... the definition changes with your mode of transportation and your final or the items/materials liberated final destination.
With societies current lose rules on copyright there will inevitably be arguments over who thought that first and thus owns it or should be responsible for it.
Thus as pirates shouldn't our stance be who cares whose it was first - If'n we want it, we'll take it, then it'll be arn.....Auurghhh!
I forsee a future of the pirate state where profit be only as reliable as the last person to claim it as theirs.
I like being able to name myself pirate, even if it is for semi fun reasons.
