Because I don't need make or su to repair a broken system.
The things in /bin (and /sbin) should be the things needed as a bare
minimum to fix other things. The simple tools to setup, fix, and boot the
rest of the system up.

I already said that I consider /recover (or whatever it was called) a bad
solution created to fix the fact that you are breaking /bin and /sbin.

Until now /bin and /sbin did hold the things needed to fix a very severly
broken system. About the only things totally unrecoverable is a broken
init, kernel or perhaps /dev.
If those are okay, and I have /bin and /sbin (or atleast most of them), I
can always fix myself up.

Have you never had a system go bad on you?

What you should be arguing (whould I really tell you this?) is why I
consider /rescue to be a bad solution, instead you're more or less asking
why I want to have tools to rescue a broken system.
