That is a feature, not a bug. Supreme Court decisions are informed by precedent, not bound by precedent. If that creates chaos it's not their fault. Blame the legislators who wrote bad or vague laws in the first place. If the laws were sufficiently clear and specific then the Supreme Court wouldn't have much work to do.

And let's not have any ridiculous claims that the Supreme Court needs to legislate from the bench because Congress is dysfunctional. In most of the areas where Congress has failed to pass new or revised laws there are real divisions or lack of consensus in the country. It's more important to preserve our Constitutional separation of powers even if that leads to bad outcomes on particular issues.
