Yes, I've been thinking about something similar. Some time limit for individual's liability might be a good compromise. If you could wait to get some things free for personal use later without being in danger of legal problems it can remove the pressure from people... And on other hand if you really, really, really want to watch that freshest movie of an audio album right now, paying for it seems reasonable? Those who ca wait probably wouldn't pay for it in the first place, so copyright holders won't lose that much, at the same time keeping happy "long tail" of people who don't want rare/old things to vanish without means to access it. I wouldn't say that it's public domain though, because I still don't think it's ok to profit from it, like just downloading a book/movie and selling it or something like that.
