Having multiple needless laws is another way to control the population. Everyone will be violating at least one law. The government will then just enforce the laws on the people they don't like.
There is a book titled Three Felonies A Day that explains this. US Federal laws/regulations are so obtuse, over-reaching, arcane and complicated that the average innocent person violates 3 felonies per day. And your point about enforce the laws on the people they don't like is one that the author makes as well.
A previous job of mine was software developer for a state motor vehicle agency. I had to read far too many state & federal laws/regulations to make the boat/vehicle registration system compliant.
Which is explicitly against the 14th amendment.
