Let's say Apple allows sideloading, but it is somewhat tedious and most users choose to stick to the official App Store [...] There is no reason that sideloading is tedious. If it is, then that is a deliberierte choice, going from no sideloading to no sideloading that anybody will care to use. Just as Microsoft was forced to suggest alternative browsers to users instead of simply bundling Windows with Internet Explorer and Edge, one could even imagine to force Apple to let the user pick an alternative app store during setup.
