> it punishes work that can't pay the copyright extension fee One tradeoff is to have the fee be proportional to the revenue it is generating. But this could encourage extension-by-default, rather than making it an intentional decision the copyright holder has to make: Is it worth "buying the monopoly rights." I think I would be ok with that if the increase for future extensions was steep. But that does also come at the cost of the second part, > that doesn't become popular until later You have a small-time creator that doesn't extend, and so loses out on massive potential revenue derived from future popularity of the work decades later. This would be unfortunate ... but on the other hand I think society would be more likely to make this true and create interesting derivative works if there were more works that were derivable. You need to keep durations short to make that happen.
