I think it would be very interesting to explore the boundaries of monopoly, and to look at cases where monopolies are probably a good thing.
For instance, trademarks are a monopoly, but I don’t think many of us want any company to be able to co-opt brand names. That seems pretty clear.
Getting less obvious, IP-protected interfaces like GoPro mounts or those dumb Kureig coffee pods. Nobody likes those proprietary interfaces, and they do give monopoly control, but are they economically bad?
And how about console games, where all of the makers subsidize low Hw margins (therefore higher sales) with monopoly control and a cut of game publishing. Would the market be better if that was prohibited?
It’s going to be pretty easy to dunk on obviously harmful monopolies. It might be more interesting to explore more nuanced cases.
