There's more to shitty app behavior than just hardware-dependent data like location, and some of the enforcement can't really be done in software. Especially when it comes to workarounds/exploiting private APIs. Right now Apple can yank an app pretty much immediately if it's found to be doing that; if the app were in an alternate App Store, a much slower OS update would be Apple's only option. Payments also come to mind: Apple has strict standards for what you have to explain to users before you take their money. (Granted they're not always perfectly enforced.) And some of the terms (like easy, clear cancellation) are enforced simply by the fact that you must use Apple's payment system. With another App Store, that goes out the window.
