You can escape Switzerland by going straight up into space. It's only "in" the EU in 2 dimensions, maybe 2.5 since you can't dig your way out.

Ah, that's what they're building the power plants for. Blasting things into space.

Maybe Tim Curry should move there.

Just the opposite. It's literally not in the EU. It's literally in Europe but not in the EU.

I like that you ignore that “in” means “inside” in one sentence and then use that exact meaning of the word in the following sentence

The term EU describes a membership, it doesn't describe a geographic area. Being in a membership means something different than being in a geographic area. So the term "in" does not have the same meaning across the two contexts.

The term EU doesn't describe a geographic area. It is a membership. Just as if I'm surrounded by members of a book club, I'm not in it.

By that light, the UK is still in the EU. I bet they would disagree though.

The UK is not enclosed by the EU.

To be pedantic: neither is Switzerland because of Liechtenstein...
