Manned border checkpoints are inevitable in that case, it would be an external border.

But of course a blockade isn’t a realistic option, the Swiss would fold immediately if they thought things were headed in that direction. You could never get to that point.

The point is that the EU can crush Switzerland with the stroke of a pen, they couldn’t crush the UK without going to war. Switzerland could never even consider a kinetic response, so its room to manoeuvre agains its vastly bigger neighbour is limited to begging for mercy.

It’s also important to remember that nobody in the EU likes the Swiss, they are notorious troublemakers who are tolerated at best and despised at worst.
