The problem is that his proposals ignore the economics behind banking. If you take someone's money and put it in a vault, how can you provide interest on that money? You can't. You'd, in fact, have to levy fees to cover the costs of staffing, buildings, security, etc. Yes, even an internet bank has to have physical infrastructure somewhere. Heck, why am I going to spend $3 for a SafeBank iPhone app when I can access…
Where real innovation and safety comes is through the idea of narrow limited purpose banks. There is a lot of space to innovate if you as a bank can focus on one product only.
The simple way of doing this is to imagine every account type a bank has as a separate mutual fund.
The checking account would be replaced by a 100% reserve 0 interest cash mutual fund, which makes its money from float, membership fees, transaction fees etc. Most checking accounts now are paying an insignificant amount of interest anyway.
Savings accounts can be offered by various levels of money market and similar funds.
If all of these funds follow the same simple standards it is easy to transfer between them, even if they are run by different companies. We are working on creating these new standards on the Agile Banking list:

One of these standards we are working on is a dead simple OAuth/REST based transaction API that we're calling OpenTransact. It allows for very simple transfers, but allows more complicated financial transactions to be built on top of it.

What about ATM fees, credit cards etc. These should be run by independent companies. On the Agile Banking list we are talking about independent card issuers. These are independent companies that offer regular payment cards that in essence control OAuth Access Tokens to an OpenTransact based cash mutual fund as I described above.
As a card issuers only access to your account is via OAuth, you as a consumer can easily manage limits and even revoke the Access Token. You are in control.
Business model for these card issuers? Advertising on cards, transaction fees, membership fees etc.
There is plenty of money to be made in this business, we don't need to keep thinking about it in the frame of how it has been done until today.
