That's what I said. But that's also the most concerning issue,  
considering that a personal computer is well, personal. The other  
people who usually have access to it are trusted and if not that's why  
you have different users. Are you telling me that you voluntarily give  
your computers to people whom you do not trust and you fear they may  
stole information from it, yet you still give them full access to your  
user account that contains that information?

And BTW, there are solutions to to encrypt you own files as a user,  
not just the whole filesystem. Anyway we digress.
