Copyright shouldn't be abolished, it should be reformed however.

It should be 20 years, with right to renew, your first 10 year renewal is free, then the cost skyrockets, with proof required that you are still using the work in commerce, and after that first term, you get a flat rate 5 year extension, then it must be renewed annually with escalating fees.

It allows the big IP places to hold on to their family jewels, but also would return a significant amount of orphaned work to public domain.
