No, Swiss Franks do not pay dividends, that's why nobody is betting on the fact that Swiss Franks would be worth more in the future. Somehow owners of Bitcoin insist that it doesn't follow this simple rule and that it should net a return.
>At some point I will hope someone (perhaps someone in Switzerland) will exchange something I want for those pieces of paper.
The amount of businesses accepting Bitcoin as a means of payment is very small. The incentives to do so are almost nonexistent. Everyone is converting it back to a valuable currency, this is why the price of Bitcoin is highly volatile. There is no minimum demand for the currency. There is no economic system that is dependent on Bitcoin being less volatile.
The Swiss government creates minimum demand for the currency through taxation. The people living in Switzerland decide to adopt the currency and thus there is an economic system that needs the Swiss Frank to roughly maintain its value. Heck, small amounts of inflation are necessary because a currency that is generating a return is highly undesirable as a means of payment. Since it's losing value over time you are discouraged from using it as a store of value. The existence of an economy that is constantly exchanging currency for goods is thus ensured.
>On the other hand the Swiss Government could decide to make the money almost worthless, practically overnight (India did this with Rupees), by removing the main purpose of having the notes.
Yes and the beauty is that everyone would consider the currency worthless. With Bitcoin there would be extremists clinging to the belief that it would retain its value.
