You can get that copy of AutoCAD from multiple sources for multiple prices. This is perhaps part of the reason why our legislators apparently lack the competence to write reasonable laws. I would also like to point out the flaws in the "you get what you pay for" comment. Obviously you should be prepared for the possibility of being punished for doing the right thing.

Until the courts agree that purchasing software is a transfer of property rather than a limited license, non-violent disobedience is acceptable because it's the government that screwed up, not you or the guy on ebay. I would suggest you define 'right' and 'wrong' by asking me, since I tend to not be as self-centered and greedy as other organizations. However, they're designation of 'right' and 'wrong' is generally developed to serve their own interest. You probably have a local church or aristocracy that would be happy to define that for you.

At some point you have to determine the difference between 'right' and 'wrong.' It's usually best to do the right thing. I should clarify the "morally justifiable" part. After all, people like AutoCAD or the MPAA/RIAA can afford do buy laws whereas people like you or me likely can't. It's just that the people who wrote the laws didn't think through how ownership should work and neglected the end user. You're willing to fairly compensate the product owner and everything. So if you can't buy a legitimate version of AutoCAD from Ebay, then it's morally justifiable to pirate it.
