If we have to have this discussion again...
we could just copy one of those systems wholesale
Maybe. But when you do out the demographics, there are plenty of reasons to think that things here are not quite the same. With different sorts of problems, the same solution isn't guaranteed to work.
If you saw a better technique for doing something at your business, and didn't do it because "i don't like to see problems solved in that fashion, regardless of what the metrics tell me", you'd be an idiot, right?
Maybe. But maybe you're constrained because of what the Board of Directors will allow you to do. By analogy, the Constitution simply doesn't allow the federal government to do many of the things that your solution would require. Even if they're great ideas, it's simply not allowed. So you should be concentrating on changing the Constitutional restrictions that prevent those solutions, rather than getting the Courts to throw out ever larger chunks of the only thing that protects us from tyranny.
