What's in it for the banks? Why would they adopt a blockchain based transfer system as you describe when they already basically have a monopoly that is making them money in higher fees and that they are in full control of?
The fees question was one of the first things I thought about, of course. I do not have a clear answer, it could be that with substantially smaller fees, substantially more people would transact (this would also bite visa/mastercard tremendously, thought about that?), and the net gain for the bank would be positive.
I am glad that some of you people that wish to integrate with the mainstream financial world at least believe in the reasons the rest of us do about having control over our finances, but you're fooling yourself if you think integration will allow you to do that. You're blind to the dangers and ignore the history of how we got in the situation we're now in, with the banking system and manipulated financial systems in firm control of the majority of the planets wealth.
Well, I would personally never use BitShares through the bank, to me it defeats the purpose. But you and me are not most people, most people do not want the burden of having even 10K USD worth of virtual tokens in their virus-prone nsa-backdoored malware-infected windows system.
Most people are not researching about crypto and mostly everyone seems happy to provide whatever information the banks/governments provide. It pisses me off to no end how the majority has become so docile and what not, but lets be practical here .. having bitshares integrated with the banking system would in no way (well, in maybe one way, which nobody has brought up yet and I'm surprised that is so.. I won't elaborate on one potential massive downside just yet) detract from your experience or my experience of the network.
