著作権についてまでモラルは問題となるのか

Since copyright is intended as an economic right (as detailed and cited in Patry's post), the arguments over copyright need to focus on the economic issues. And a properly calibrated system is one where there's the greatest overall economic good and everyone has the greatest opportunity to benefit. At that point, where's the morality question at all? The answer is that there isn't one. Claiming morality in an economics discussion on copyright is a crutch used by those who can't support their position. There is no moral issue at all.
