>And we had to live under the ambiguity for more than three decades because the law was so poorly considered, and it's still not clear exactly what it covers.

No, we lived with that ambiguity because the US system of laws purposely chooses to let Judges in the court system decide those ambiguities (and create "precedent") but only after something has happened, only after that happening leads to a court case, and only if that court case is not settled or dismissed.

That means everyone can just settle cases that would lead to a precedent they don't want.

US law ambiguity is purposeful. The solution is that we should have judges and courts that emphasize the outcome to normal people, and endeavor to improve justice to normal people, but all the people who get law degrees seem to be somewhat sociopathic and prefer instead to waste millions setting precedents on what individual words mean (that don't match at all what a normal and reasonable person would understand) and police syntax.

Judges who try to do just that are labelled "Activist" by politicians.

Meanwhile, when we have agencies who take it upon themselves to take a vague law and turn it into much less vague rules and clear recommendations, they are accused of being unelected bureaucrats writing laws.

If you want less ambiguity, you need to elect people that don't punish agencies for putting out clear documentation, and you need to reform the entire justice system to prioritize clear readings of plain language law over our stupid system of treating english as a programming language for law, which it can never be.

Human language is ambiguous. Law will always be ambiguous. If you suggest instead we should use more strict language in law on a forum full of programmers, you should hopefully understand how that is a cure far worse than the disease. You will end up with law exactly as unambiguous as it can be to an army of specialized lawyers and nobody else.
