It's not right. Actually right now if you deposit 1000$ the bank can loan 9000$... so it's not the same with BTC.
Uh? No, cash is cash is cash.
As long as people want to hold actual real banknotes, banks can't "just create money".
What you are talking about is fractional reserve banking, which can be done with bitcoin too, as long as people accept money on a bank account instead of the actual bitcoins in your address.
Either you compare bitcoins with actual real cash you can hold in your hand, or you compare virtual dollars sitting in a bank with virtual bitcoins sitting in a bank.
No difference.
Two differences. There could be no government depositor insurance, as the govenment would not have the money. People would only save in safe banks. There would be no money printing or QE, meaning the so called bank reserves of today would have to be replaced by equity. I suspect fractional banking would be possible, but less relevant.
