I've literally never seen anyone use the word "cute" when NOT referring to a child or an animal, if they are NOT trying to be condescending. So that's off-putting right off the bat, but everything else in your comments suggests that you simply don't know what the word fiat means.

Fiat means 'by arbitrary decree'. That means that fiat currency is currency because someone says it is. Generally no problem so far, if everyone agrees to use that currency to represent value. 

But in the USD and the fiat I'm aware of, that decree declares 'this is the money available for you to use, it necessarily WILL be worth less tomorrow. If all goes as WELL as it possibly can, you will have 8% less value next year. If WE need more value, we can just produce MORE of this currency, making your saved currency worth MUCH less, so WE can extract that value from you without doing anything but 'printing' more of this currency". 

COULD there be better fiat? Absolutely. Create a fiat that can't be inflated, that can't be devalued by creating more. 

If government created a fiat currency that COULD NOT be 'printed' at will they would make it useful as a medium of exchange without making it damaging to the wealth and value that those who work for it posses 

But they don't. Because then THEY would have to do something for the money THEY want too. And that's the basics of the system we have: They offer a currency that WE have to work or trade for, but they can just create at will for themselves. That is inherently unjust for those who have to work for it.

All that said, if 'government not stealing value from you every day for  work you already did' is now "utopian thinking" then yes, I think you'll find MANY 'utopists' holding bitcoin.
