That's the way OSX is RIGHT NOW. As a User I can run any program I want and mucky-muck my crap up. But Apps from the Mac App Store live in neat little bundles and are forbidden to do the mucking around in OS bits. So the OS is an "appliance" that I can just replace at a whim. If I go off the tracks to load apps that NEED to overwrite OS space, then I know who did it.

Personally, I but App Store versions whenever possible and I have next to zero problems with my Macs an order of magnitude less than my locked down PC at work even. VERY few apps need to color outside the lines and I like the push for them to explain themselves or get blasted by the next OS update.
