The unintended consequence of banning nation specific licensees, is that you'd essentially be giving a huge advantage to the already global services. Any service that isn't global, wouldn't be able to compete with those who already are.
Netflix is global, Prime is on its way, and Disney and HBO are trying. But a BBC streaming service is going to outbid 10/10 times because they can't afford to buy North American streaming rights when they don't have a (viable) North American service.
The BBC would survives because the law mandates UK citizen pay for it. But any non-subsidized local service would be dead in the water.
Don't you think it's a good thing if public money from the BBC is used to develop interesting programs instead of subsidizing Hollywood blockbusters? Who cares if i can't watch Spiderman on BBC STREAM? I've got torrents for that :-)
More seriously, Netflix business model is deeply broken. Trying to replicate that at all cost with public money is doomed to failure. A decent alternative would be the Global License [0] which was at the center of french public debate 15 years ago. It's more or less the same model, but without trying to feed ~parasites~ shareholders on the way, and without stupid competition between 5 different streaming services you all need a subscription for.
