I would like to read opinions on what copyright should be.
It's a big mess as it exists today in the US. Not sure bout other countries; not sure which has the best handle on it. That it is violated on so many levels, from individual to organizational, means it is not working well. Content creators and copyright owners are rightly due their just compensation. But without users willing to play, it becomes merely an empty exercise, scolds having little impact.
In my opinion, as a start, if the goal is to maximize royalty revenue, some loosening of the fair use rules must occur; copyright regs for commercial use must be distinct and different from amateur and/or non-profit regs, so that the many who violate the law have respect for the law and become self-policing. I think most of the copyright violations are among amateur music groups and musicians; and I think that if everyone hewed to the law obsessively, there would be far fewer works performed, and, indeed smaller sales revenues than today, because many works would be less well known.
