Probably because you can’t even properly `ls` system directories without it.

What would you do in the terminal without it?

Because it is useless without?

lol, is this serious? The final straw with Mac for me was when I accidentally hit “No” when asked if I wanted to give my terminal access to the file system. All of a sudden I was starting my work day without a working terminal. Obviously there was a solution, probably an easy one, but I didn’t even look for it.
