Why "make a case" in the legislation?
Isn't that best left the debate whether to pass it?

What the heck does a mere opinion accomplish when written into the law?

It is actually common. The findings provide an understanding of the "legislative intent" of a law. The clearer that intent, the less wiggle room there is for judicial interpretation of the law.
