Aight but the whole "be your own bank" thing depends on you maintaining your own full node. Otherwise you might as well be using PayPal. It doesn't do much good signing transactions if you don't also have a record of all the other transactions. I mean, centralized services could just as easily implement a "sign a message with a key" option for authorizing account actions. The whole point of bitcoin is keeping track of the public ledger so that nobody can get away with inflating the supply of money or double spending already spent outputs. These are the things that you cannot do, and by my estimation this makes you *not* a bitcoin user.
