I'm sure in some alternate universe, someone else could have come up with the ideas for star wars and raiders if GL did not exist. He wasn't the only person in the universe to have seen old movie serials.
That still does not address that Lucas is on a mad quest to destroy the original versions of the SW saga, THX, and american graffiti; and he appears to be succeeding on that front with the advent of the absence of the LOC safety net. Private owners of the OUT are going to be under threat in matter of time to surrender their copies to be destroyed by LFL. Do you think GL/LFL cares about private ownership rights? They don't,because corporations like LFL have more power that they have had in the history of incorporated businesses, I keep saying this, big corporations are able to supersede any law in any country to make a profit. So we have keep open the idea that the OUT may actually be lost. No one wants to talk about this scenario, but we should.
