The EU would have to rely on German, Austrian, French and Italian cops/soldiers to actually enforce any sort of physical blockade against Switzerland.

I am not certain if all the respective governments would simply obey such an instruction if they didn't have any beef with the Swiss themselves.

Which now means that the EU has to block not just Switzerland, but (say) Austria, which means compliance from four other countries (CZ, SK, SI, HU), which is even less probable etc. etc.

Ultimately, the EU is really good at processing papers, but doesn't have the power necessary to initiate physical punishments of this sort unless the relevant member states agree.

Trade policies are very much set at an EU level.

Without these treaties, there absolutely will be permanently manned border checkpoints.

None of these countries love Switzerland enough to be willing to end the EU over it.

Manned border checkpoints are likely in that case. I don't believe in complete blockade, though.

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.
