If I asked you for $10 and you offered me 10 CHF, I'd probably turn you down, as despite 10 CHF being worth more than $10, it's still effectively worth less to me, as my buying power from 10 CHF is significantly lower than it is with $10. I can't pay my taxes with it, I can't buy dinner with it, I can't pay my rent with it. I can't even store it in my bank, I have to pay to convert it first.
I suspect most people (especially in the USA, given how relatively few people even leave the country compared to other western countries) don't consider foreign currency to be real.
Heck, try spending Scottish Pounds in London (UK) and see what responses you get.
