2. there is no demand, again the difficulty to obtain makes it unusable by 99% of people
Well, every new technology faces the chicken and egg problem. This is already known.
3. I dont pay the bank anything, cash at home is more than secure as well
4. get a new card for free or use cash
6. I dont pay the bank or my credit card for protection. In fact I make money with rewards
Only some types of accounts are free (the most basic ones), and even then, they're not entirely free. The fact that they receive your money means they can spend it on something else while claiming they still have it (this is fractional reserve).
About #4, if your cash gets stolen, it's lost for good. If your card gets stolen, you get a new card, but an insurance company has to pay for it. There's no reason why there can't be a Bitcoin insurance company (although it would work a little different from what we're used to).
5. yes, but certainly the black market is the most obvious utilization for btc. thats the only real new feature it brings to the table, a way for criminals to work online and avoid things like paypal
Black market has been working with cash for as long as there has been cash. If I were you, I would stop using cash because it's being used by drug dealers and other kind of criminals.
