As with most laws they are put in place because someone tries to take advantage of someone else or deprive soneone else of what is rightfully theirs.
The law-abiding citizens are the ones who pay the penalties because the law breakers will continue to break the law no matter what. They seem to think that they have an exemption certificate that entitles them to do what they like when they like - and to squeal like stuck pigs when someone stops them.
