You need a compiler to build iOS and OS X apps. Once you have a compiler on your machine, how can someone else prevent you from creating or running arbitrary executables? In order to lock down the desktop so as to make a Mac App Store the only way to obtain executable content, Apple would have to fundamentally re-invent the way people build iOS and OS X apps. I just don't see developers sticking with the platform once Xcode is a hosted web app. Chasing away their developer community would effectively cede the market for mobile apps to Android. Apple's strategic, long term focus is clearly and unambiguously "mobile computing for the common man." Providing a dirt-simple app distribution platform makes sense within the context of mobile computing. Making it substantially harder to create iOS apps, relative to other mobile platforms, is contrary to Apple's strategic goals.
