> If laws are ambiguous, governments run the risk folks will conclude they'll get in trouble no matter how diligently they try to suss out the spirit of said laws

Well, yeah, but that's the goal. People will correctly conclude that their ability to act unmolested is entirely contingent upon remaining in the good graces of local and remote authority figures. This produces extreme chilling on dissent or disagreement and promotes deals, bribes, and bootlicking. The law is transformed into a transparent legitimization mechanism for what the powerful wanted to do anyway, applied and ignored according to the real power structure adjacent to the legal bureaucracy. This is the default state of human civilization when the rule of law is not proactively defended.
