I don't need to know where the rm command is in order to use the which command.
I *was* (knowingly and deliberately) assuming that you have a semi-reasonably
working system, and that your question meant "given command X, how do I
find where the executable X is on my system?".
Sounds like you want to make less assumptions than that. Fine. but probably
best to be clear about your assumptions up front.
