So you think people trust fiat money because they can use it to buy food/rent/gas? How about Euro then, you can't use it to buy these things in US either
I don't use euros in US. Everyone uses dollars here. No groceries, landlords, or gas stations that i visit accept euros, either.
If you're interested in learning how euro is different from bitcoin, i'll be glad to give you a detailed answer.
Exactly, as long as you are in US, you can't spend euro to buy anything, but you can always go to an exchange to convert them to USD
Same, if there is no one accept bitcoin around you, you can't spend bitcoin to buy anything, but you can always go to an exchange and convert them to USD
Unfortunately, that's simply not true. If you know of an exchange where i can turn my bitcoins into dollars, i'll gladly use that exchange to play the spread between Gox & Bitstamp. If by "exchange," you mean some place on the interwebz that will take my BTC for a promise to give me a few dollars sometime in the future, i'm afraid i'm already there

If bitcoin was no different from any other currency, we wouldn't be having this discussion, would we? It's quite different, if only because there is no Foregny that issued it.
It's not *fundamentally* different, of course.
If a state with no land, no foreign reserve, no economy & no political clout issued a currency, and a bunch of currency traders started using that currency as chips in a game of bluff, you'd have something very similar to bitcoin.
