Not to side on the side of onerous regulations, but this is a little naive. There is good reason that many of these laws are as long as they are. Things have to be explicitly laid out in legal language.
Still, laws must be written before they can be enforced. Some adjustment should be expected. I've occasionally wondered if it would be possible to have a "Deletionist Party" who's sole political aim is simplification of the legal code.
I think they would quickly find out why there are the nuances carved out in the legal code. Writing laws for millions of people, let alone 300+ million, is insanely complex.
