Because an app being on the App Store creates an expectation that cannot be met without the sandbox.
Without the source code and large amounts of resources it is not possible to determine whether an app is malicious or not. The only way would be for Apple to trust that developers actually do what they say they do. The unfortunate reality is that they cannot be trusted. I don't blame Apple for not taking that responsibility. Unfortunately that means the responsibility ends up with the user who cannot make the determination either. Such is life.
Many app stores (even for smartphone) have sandboxes where you can grant additional privileges. Of course the user (who else) has to decide whether they trust the app or not. But I'd be happier trusting a sandboxed Dropbox, especially because it couldn't have hidden its use of Accessibility.
