That's the only positive aspect I see to DRM: it does seem to calm some of the knee-jerk "but they'll steal me blind" reaction on the part of the authors and publishers, which in turn allows them to consider the idea (more) rationally.
In their defense, the matter that we discuss in so clinically detached a manner, is to them food in the mouths of their families and themselves. It's shouldn't really be a surprise to us that they are rather ... concerned about it.
The reason I don't choose to take an absolute "No DRM" stance myself -- though I do not, in any way mean to disparage those who do -- is both that I recognize that fact (and find it quite compelling), and that I really think that in the long run, this DRM thing will either shake out to something we can all actually live with (on both sides of the matter), or the world will reach a point where they realize that it's not actually helpful and drop it entirely.
I don't have problem, personally, with being prevented from copying an e-book wholesale, as long as I can read it as I want on whatever media I like, and can lend/give/sell it. If a DRM scheme comes down the pike that permits all that, I really think the matter will become moot.
