You're missing the point; yes, there are bad laws and righteous ones, laws that protect private interests against public ones and vice versa, and laws that are passed solely for political advantage. I agree.  

But  . . . law is just about our only modus operandi if we want to live under the rule of law--ie. not the rule of force--in the "more perfect union" desired by the Founders. 

People are simply not ready to either live without or strictly abide by laws, if they ever will be. But that's not a reason to forego legislation and law. Battle rifles need to be banned, by law.
