That gives me an idea for a copyright scheme.<p>By default any work is protected by copyright for 30 years.<p>After this point the copyright can be renewed for 10 year periods, with the cost increasing each time. Maybe the first extension costs $100, the second $10,000 the third $10,000,000 and so on. Put a cap at 7 extensions for a total of 100 years. Inflation makes all of this tricky, but if its all based off of a base price which is pegged to inflation and then the extensions are multiples of that it would work fine.<p>I&#x27;d argue that a longer monopoly on a work is more burdensome on society so it makes sense that it would cost more. Maybe they can reinvest the fees into the  patent office or something.
