You could offer a grace period (lets say 1 year) to give time to people to register their post if they want. Same as with the reform to Patents which occurred last year.
This will still favor sophisticated creators/content owners.
I see the advantage of your system when coupled to an increasing price for maintaining registration (it would flatten the plot in the original submission). But I don't see the advantage over the solution of a short-term copyright: your system would basically keep out of the public domain important works that already benefited the content owners more than enough...
Well I feel it's a compromise, large corporation like Disney will never yield, what I'm trying to avoid is them causing other works that are no longer in print or distributed from disappearing. I want to give a disincentive to keep things under copyright for ever.
"your system would basically keep out of the public domain important works that already benefited the content owners more than enough." While true the exponential rise in cost in my proposition would lead to ensuring that these things will go into the public domain at some point. As it is now, extensions apply to everything including things for which no one cares for anymore.
Let's not ignore that the current system is also biased towards large corporations anyway. The cost of enforcing copyright is prohibitively high for small creators. I also suggest in a previous post to have a open databases showing registration (paid for by the registration fees) that would make it easier to find and contact creators to license their things.
It would still be a huge improvement over our current system, where the majority of works enter the copyright blackhole and become inaccessible because they are too old to be profitable yet too "new" to be in public domain.
