Laws are not set in stone (and when they were, in Hammurapi’s time, it didn’t help much), and some laws are clearly stupid and vicious. For example, in imperial China, it was once illegal for an ordinary person to keep astronomical tools at home (if I remember corectly, there was a death penalty for this). I believe copyright laws are just like this.
>> you are doing something wrong and...
>> keep doing it if you wish?
Because we believe there’s honestly nothing wrong with it.
Paraphrasing you: I don’t understand what is wrong with accepting that pirates are doing something right and... abstain from doing it if you wish?
