Anyone who's ever nervously handed their kid their phone so the kid could play Angry Birds for a bit can tell you why Android's method of handling users isn't perfect.

That's why it's great that Android supports multiple users on a phone. Setting up a guest user is easy, and setting up a dedicated user is only slightly less so.

I'm not sure what software level protections can stop your phone from being dropped down the stairs.

You misunderstand. Android users are different from Linux users. :)

Android runs Android applications each as a different Linux user.
