I would argue that in a digital world, copyright should be inversely scalable to the size of the creator - that is, individual works by independent artists intended for exhibition rather than reproduction should receive more favorable terms than movies or games created by huge conglomerates intended for mass reproduction, licensing, and sale.

Or more simply: if you’re not selling it presently, you don’t get copyright on it. There, abandonware and lost media rights are solved, and we can all move on.
