The government should make laws that protect the citizens from hurting themselves and or others (for obvious reasons).
Most laws are needed but some laws are just silly such as: in Alabama it is illegal to carry an ice-cream cone in your back pocket, in Maine you can't tickle a woman with a feather duster, in Utah you can't carry a violin in a paper bag, in Tennessee you can't sell hollow logs, in Kansas you can't serve wine in teacups, in California you can't ride a bike in a pool, in Connecticut pickles must bounce to be considered actual pickles, and in wiscomsin you cant serve apple pie without cheese (these are all real, you should look them up).
People can be counted on to scoff at these laws or even be unaware of their existence.
Hope this helps, I certainly had fun writing it lol.
