No, tangible items are inherently controllable because they are rivalrous and excludable. The law just structures how we deal with those characteristics. For information, copyright attempts to make it rivalrous and excludable, to stuff it into the same box as tangible items when it shares none of the same properties.
1. First of all, [citation needed]. Humans have been exploiting information asymmetry since the dawn of time.
Sure they have, but just because it happens sometimes does not contradict the self-evident fact that people love to share. Next time you send someone a lolcat, remember that.
2. It is also "human nature" to want to want to have sex with people one finds attractive. Are rape laws also never going to "work out"?
Rape, murder, theft, these are all behaviours that are (1) not the common case and (2) inflict harm because the objects of the crimes are essentially rivalrous.
3. Entertainment counts as "knowledge" now? That's even more of a stretch than calling it "culture"!
Arguments about quality of the information are completely orthogonal to the topic. Copyright law does not attempt to discriminate on the quality of the material copyrighted so quality isn't a factor in discussing the merits of copyright law either.
