Personally, as copyright is a non-natural right, we should limit it for films/tv/shows such that whatever price it is sold for, then it is made available for any distributor to sell for after a very limited monopoly period (1 year from release, say, reflecting the current market in which films go from cinema to TV streaming platforms in a few weeks). This would apply to all distributors over X users and/or Y revenue (taking in at least the top 5 streaming platforms).

This way, the public can access copyright works, and producers of works can be paid, but distribution is opened up. Creators still get paid, distribution isn't monopolistic.

Netflix can argue "this show is worth £5 per viewer" and only sell rights at that price, but they pay tax on that price, and crucially the rest of the catalogue then needs to add up so if viewers are paying £8 per month then the rest of the catalogue is marked down accordingly. There will be manipulation, but if it doesn't reasonably add up then apply the sort of penalties in the EU of 20$ gross profit fines; strike off directors for copyright abuse (can't be directors of media companies again).

I can't see that this would harm income for creators, only for distributors (who aren't needed, they're just duplicating using monopolistic practices), and it seems it would have broad appeal.

So, yes, I agree.

That's not comparable. Netflix did not have a monopoly on "shipping DVDs". Plenty of retailers, online or brick-and-mortar, did that at the same time Netflix did, and video rental places were still going. Some of which would deliver movies (the local Marcos near me had a deal with a local Family Video where if you bought a large pizza they would bring you both the pizza and a movie of your choice from Family Video, assuming it was in stock).

Nor has Netflix had a monopoly on streaming.
