And I often have done, usually after getting tired of seeing 'command not found' for the umpteenth time. A lot of Unix-ish systems put fairly innocuous and commonly used stuff like traceroute and ntpq there.
One obvious problem with removing permissions on all this stuff is there are sometimes situations where an ordinary user legitimately needs to run, say, mount.
