As opposed to waiting for uncertain court cases (based on the existing shitty laws) to play out for years, ultimately decided by unelected judges?
Democracy is the worst system we’ve tried, except for all the others.
(Also: The GPL can only be enforced because of laws passed by Congress in the late ‘70’s and early ‘80’s. And believe you me, people said all the same kinds of things about those clowns in Congress. Plus ça change…)
Courts applying legal analysis to existing law and precedent is also an operation of democracy in action and lately they've been a lot better at it than legislators. I don't know if you've noticed, but the quality of our legislators has substantially deteriorated since the 80s, when 24-hour news networks became a thing. It got even worse after the Citizens United decision and social media became a thing. "No new laws" is really the safest path these days.
