True, but all goods, services, your wage and taxes are priced in fiat,
if you don't express btc in fiat you don't even know what your purchasing power is.
What is the purchasing power of 1 btc? Oh right, you need fiat number even to comprehend the meaning of 1 btc.
Your analogies are trivial and unrelated to my point in lame attempt to somehow justify the bitcoin.
This is because for now fiat is more important. But things change.
The difference is that if poeple really wanted fiat in the first place bitcoin would not exist.
So what you want is purchasing power and means to keep it or transfer it.
Now we use fiat to price things, we will see how long that will hold.
What you guys fail to understand bitcoin is not a currency itself, it is just a tool for transacting currency. When you send someone 1 btc, or when you buy something with bitcoin, what you're doing is you're sending him 320 dollars via bitcoin, you're sending him purchasing power of dollar.
Bitcoin is not independent of fiat. Actually, fiat is what gives bitcoin a value.
