> Federal "net neutrality" regulations freeze into national law a particular formula for access

Er, no it doesn't "freeze" anything. FCC regulations of other regulated industries are very frequently updated. And regulations, while given force of law by the laws authorizing regulation, are not the same as law particularly with regard to being "frozen", as they can be changed by either changing the law on which they are based, or by change through regulatory process. They are, therefore, strictly less "frozen" than law.
