Essentially every regulating agency will have to get their charter re-written and passed through Congress a second time. While that happens, we can expect to see a flood of cases decided under a variety of standards in lower courts. I think this is going to end up making real mess, it's definitely going to slow regulation and enforcement across the board.

More likely a limited subset of those agencies will survive that process due to ongoing efforts of folk whose self-confessed long-term goal is the "deconstruction of the administrative state". With this ruling, all they have to do is do nothing, or obstruct the passing of any law that attempts to return to the agencies what the supreme court stripped from them.
