That's nonsense. Who interprets the Constitution in your fantasy world? Everyone for himself? Judicial review has been our tradition since the Republic's earliest days.
That looks a lot like a False Dichotomy there, Mr. Jazz. "If the courts don't decide for us, nobody will and it's chaos." I don't have a ready answer for you, I haven't thought about it (more important hings to do with my life), but I can observe the current method of Tyrants in Robes needs improvement. There is too much deference to Judges, and until we get better ones who respect the document to which they say they swear fealty, it's not going to get better.
Which seems "A-OK" to one who likes those disrespectful decisions. If a Judge decided tomorrow that Philly can't regulate waltzing yahoos with guns, for example, you might change your mind about how wonderful judges are. Pennsylvania state government is, fortunately, coming around about this, as are most states.
