If it were really 'any' in the philosophical sense, cash would be outlawed. So no, it is not 'any', it is anywhere between more than a couple of hundred to a couple of thousands, depending on what the police or prosecutor feels is reasonable.

What is wrong with a (couple of) thousand euros?

You are describing smuggling, I was talking about normal domestic use.

There's a thin line between smuggling and wanting personal money to be somewhere else.

I get why most states want to track cash coming across their border, but it's really none of their business if they can't prove theres a crime.

The absence of a crime does not constitute a crime.

And now the funny part: even after they failed to prove there's a crime, the Swiss police still often refuses to release the money.

The state doesn't have unlimited power, so no. What you expect to see where cash is being banned outright is a slow erosion of less common uses, larger amounts, and an addition of inconveniences and risks in order to drive people off it so that an eventual ban is less unpopular or is even popular. ("screw those bank distrusting weirdos!")

To ban outright risks backlash and failure.
