A) We do not have effectively enforcement of IP law, and to the extent we do it is only because you already helped usher in a dystopia by centralizing power with entities such as Apple.
B) That laws are different in different places and that even in the US there are exemptions to laws should not be casually ignored by assuming one narrow interpretation of a set of laws as you have: Apple controlling the distribution model with cryptographic locks hard-codes in a subset of American IP preferences around the world.
C) Even if we ignore these details and take your argument at the face of it and accept that for "choose how to distribute Fortnite" you merely are deciding between one of two centralized actors, you seem to be carefully trying to perform not one but two sleight of hands on the moral discussion at play.
It isn't like Epic doesn't have legal control over how Fortnite is distributed regardless: if Epic doesn't like Apple's terms for their App Store in the current model, they can choose to just not give you the software at all. You are just hoping to play a super dangerous game by assigning a single negotiator between your community of users and Epic in order to try to convince them to develop their software differently, for which you are apparently willing to pay 36% more for your software (which means you must value it a lot: like, for whatever benefit you think Apple is getting you here you are willing to dig into your own pocketbook and pay multiple extra dollars you otherwise wouldn't have to pay on every purchase or subscription) and--and this is where the tradeoff is unacceptable and the subject of the following #2--give Apple a large amount of control over all software in all jurisdictions... control which they lie about the benefits of, which they have routinely abused, and which can and is take advantage of by external actors.
And really, that is the most important thing in all of this and what I'd hope you would appreciate if you watch my talk: by giving Apple control over all software on the App Store you give them the power to affect what kinds of software is allowed to be built by anyone anywhere while creating a centralized chokepoint for the enforcement of whatever rules that bad actors want (such as the inclusion of end-to-end encryption carbon-copy features in applications or whatever). Giving Epic control over the distribution of Fortnite can't usher in a dystopia.
X) BTW: note that Fortnite is attempting to be some kind of massive metaverse service with a centralized set of servers attempting to provide an ecosystem of content that they would then have centralized control over. If the issues with Apple weren't so dominating and glaringly dangerous today maybe we could be having an argument about whether what Epic is building is moral and whether laws need to exist to stop it (and instead force--either directly or indirectly--such technology to come into existence in a way that is itself decentralized).
