Promote it? Its part of the law of many states. If you have a bank account in any of those states, its not about promoting it. The UCC is in effect there as adopted. The point is that it is far better to study contract law, torts, constitutional law and other underlying law than to merely study the UCC alone. That is why even law students choke on it--its highly advanced and multidisciplinary. For example of the kind of boggle I'm referring to, few people seem to realized that banks are just glorified accounting firms.
