That’s a large leap. It’s not in the EEA but is in the EFTA, so even fewer EU regulations apply than in Norway, for instance. Furthermore, the EU is a much larger political entity with its own parliament and other institutions, as I’m sure you’re aware, and these don’t have direct jurisdiction over most aspects of Swiss law as they would for EU member nations. It’s a more straightforward process for Switzerland to nullify its bilateral agreements (as is threatened seemingly every few years) than for something like Brexit.
