You can have this! Simply only download apps from Apple's store. Apple still has no right to interfere in any way at all, or collect a tax, if I want to sell an app to someone else outside of it.

But the fact is that Apple has a right to determine what apps are on their platform. No different to how supermarkets choose what items to stock or social networks moderate what content to show.
