No, they are right. In the US national, state, county, and local laws all interact with each other and there is rarely an easy way to get clarification when the statutes are vague and things are mostly done by regulations which may or may not be posted in a publicly available and findable location. Then the odds of the publicly available information being up to date is pretty slim. There is rarely any notification of changes, and if you travel 30 mins to the next town they might have completely different laws with different enforcement methods.

Hell, a lot of statutes have been invalidated by court cases so the laws are on the books but cannot be enforced. I imagine most other countries have a similar blend of different laws at the local and regional levels and weirdness due to litigation.

It really is impossible for the average person to know complex law unless knowing the law is their job, and even then nobody knows all of it and all regulations.

That doesn’t mean it is slavery or fascism and that is there this person’s valid complaint turned into loony tunes territory.
