Thing is, however we leave, that's just the START of the issue.
Our politicians and government are going to be doing nothing else for something like fifteen years. Because unravelling all those treaties and negotiating a new relationship with the remaining EU countries is a really, really big thing.
And we're also going to have to cope with a lot of industrial changes and massive unemployment and the departure of whole industries.
There is no end to this. Not in my lifetime, anyway.
