Lawmakers also make and pass laws because it's their job, not because a new law is needed. They feel it's literally their job to come up with new bills to pass, for no reason other than "it's my job".

Imagine a society so stable it doesn't need new laws or rules. All the elected representatives would just sit around all day and twiddle their thumbs. A bad look in their eyes.

This is how it should be of course.
