"The Campbell had orders King William had signed"

So over here, Charlie talks about the way Brexit is going.

Charlie's scenario ends with the UK re-entering the EU but without the previous exceptions; going to the Euro, full Schengen, and so on.

I think this is an excess of optimism.

First off, it's really not clear there's going to be anything in place able to do the negotiating; a collapse of legitimacy is not inevitable, but sure seems likely.  (Food shortages are an inherent collapse of legitimacy.)  Having the monarchy step up isn't impossible, but the EU's response to a direct overture from a crowned head nigh-certainly involves insisting on a legitimate -- that is, democratically elected -- government.

Secondly, and much more importantly, getting rid of governance is the point to the exercise.  Sane people who are willing to acknowledge the idea of facts and that there are actual facts which are a constraint on what is possible are able to recognize that money is a social institution, not a material thing.  It's only real if we all agree that it's real.  The folks pushing Brexit aren't in that category of sane people.  ("Government is bad" started for racist reasons, but then Randite economic delusions got into it.  Brexit is just another manifestation.)  They truly believe that money is as natural and as pervasive as gravity, and if they could only get rid of the government entirely they would have more money because all those regulations would go away.  (Regulations are mostly there to keep your commercial practices from being either fraud or lethal.  Might want to keep that in mind the next time you hear someone complaining about regulation.)

This is absolutely barking mad in several ways, but, well, if you model post-1990s politics as the Mob taking over it's surprisingly plausible.  No rule of law would be something they wanted.

(If you are in the UK, you might want to think about water purification.  Your modern gravity filter system is surprisingly cheap and compact.)
