Archival is extremely important and one of the side effects of copyright schemes is that they limit its viability. The less access people have, the more likely some work becomes lost forever. I've seen it a few times already, with recent work, but in one or two hundred years we're talking about libraries of art that could have been preserved but are just gone.

Closed source software, that's actually distributed to people, has all kinds of problems beyond that too. Tons has been written about that, but from an artistic perspective, I think the biggest loss is that people can't legally expand the original work. Giant franchises with a central cultural presence get walled off and usually just go through a huge creative decline, which is crazy because there's millions of people preoccupied with the concepts from the franchise who are barred from using them to express themselves. With software in specific, if it's open source you can modify it, fix it, expand it, maintain it, whatever - there's all these great resources they could use, but we won't let them.
