It's not at all obvious whether copyright net protects or destroys the little guy.

It definitely does some of both, and we have no obvious measure or counterfactual to know otherwise.

You also have to take into account not just if optimal reform or optimal dismantle is better, but the realistic likelihood of each, and the risk of the bad outcomes from each.

Protect even more conceptual product ideas seems pretty strongly like it will result in more of a tool for big guys only, it's patents on crack and patents are already nearly exclusively "big guy crushes small guy" tool, versus copyright is at least debatably mixed.
