To amplify that a bit, in terms of accessing the file system, it's a pretty common security assumption that physical access and root access are equivalent. Since my phone is the system where I trust physical access the least, by extension it's the one where I'd most want a security model that doesn't assume that one can't read the file system the most. For my purposes, the chances of an attacker having physical access to my systems in a rack in a major data center approaches 0%, whereas the chances of an an unauthorized party at some point having access to my phone approaches 100%.
