Copying other people's stuff and giving it away isn't "sharing."
If you want to share, create your own work and give it away for free.
I would not dispute this sentiment. The problem is that there is not, in general, a bright line between "copying other people's stuff" and "creating your own work." That is the essence of pretty much all disputes about copyrights/patents.
There is a reason Star Trek had such an affect on society/industry/science. "To boldly go where no man has gone before.." That appealed directly to our species sense of adventure/curiosity.
Plus, Kirk always got the hot chicks.
