I can ignore that too, you know. Not all laws are reasonable.

Breaking the speed limit can be lethal. That's a pretty good reason to follow that rule even if you don't care who made it.

I haven't found good reasons to keep copyright law (on the contrary, I constantly see it hinder progress in society), so I ignore it.

If I get prosecuted for doing copyright infringement, I'll take it with pride.
