Perek 9

Why does the passuk even have to state that if the Anan stayed in one place then Bnei Yisroel would stay in one place? Obviously if Bnei Yisroel is traveling by following the cloud then if the cloud stayed they'd stay.

Ramban simply adds that this is even in a place where Bnei Yisroel think it is bad for them, and they complain about it, even so they should stay.

This is not Ramban's verbose self so I wanted to know why he would even make such a comment. I came up with the thought that this is a precursor for other places where Bnei Yisroel are going to sin by complaining and going against Ratzon Hashem, and maybe this whole detailed description of following the Cloud was a way of setting guidelines for Bnei Yisroel in the hopes that they would take the same discipline and apply it later on.
