I believe that, in general, supporting the law is good. Even in case of laws one deems silly. Even in a country where the lawmaking is somewhat corrupt.
Getting picky about which laws I obey would contribute towards social climate of not respecting the law in general. There are countries like that and their societies suffer as a result.
On the other hand for some laws the benefits of breaking them outweigh the above downsides.
The people who say that copyright laws are evil are generally the same people who say the laws that make DDOS attacks a felony are criminalizing "the digital equivalent of a sit-in"... but only when the DDOS is being carried out by people they agree with.
I can't speak for everyone, but when the US gov or the MPAA DDOS's a website they disagree with, I'm not angry because what they are doing is illegal, I'm angry about the hypocrisy in declaring something to be both legally and morally wrong, except when it serves their purposes.
