I agree that getting work in public domain is good but for someone to create they need to be motivated and I can imagine perpetual monetary returns are as good as they get... I would be motivated by something like that -right or wrong comes later - motivation to create comes first and that to my simplistic mind appears to be prompted by this high return more often than not....am I on wrong end of the stick here?
If I am not, then the right answer would be to keep up the motivation to create and keep the greed in check - somewhat like tax process. I have to give tax on what I earn so perhaps the time limit to copyright must have the hard stop as a way of community imposed rule rather than an expectation that a creator will willingly part from a benefit...
I mean tax is imposed because rarely anyone will be willingly paying tax unless it is imposed by the law so I can see a good reason to support a time limiting law but to expect creators or artists to support that law might be expecting too much from mere mortals.@jankoekepan @rysiek
