Ok:

 $ sudo chmod o-rwx /
 $ ls
 bash: ls: command not found
 $ ps
 bash: ps: command not found
 $ pwd
 /home/dave
 $ cd
 bash: cd: /home/dave: Permission denied

Uh oh. Good thing I ensured that I started a root shell in another
window to fix the damage *before* I tried this ill-advised experiment.

As for the other poster's question: in general, users need to see other
directories, like /bin and /etc. There are some convoluted ways to do
what you want, but you have to decide for yourself whether tiny gain in
security is worth the significant effort and deep understanding needed
to do it.
