This analysis is incomplete. Under this scheme, if someone cracks
your account they can install trojaned or malicious executables owned
by you without cracking root. The flaw is in believing that this
scheme requires an intruder to crack two accounts to defeat your
security. In fact, you have doubled the number of targets but left
the amount of work required of the bad guys to compromise your system
the same (crack one account).
Put all your eggs in one basket, and WATCH THAT BASKET.
