Honestly, in my opinion this could not be a more misinformed take on the reality of banking. Today there exist no alternatives to commercial money (private bank debt), because our governments' demand taxes in it.

Finance and banking are also different, yet you seem to use the words interchangeably.

Banking = creation of credit.

Finance (today) is about creating overly complex financial products to take part in the game of high volume automated trading, such as with the use of BlackRock's Aladdin - where the same financial products are sold and resold hundreds of times in an hour. Pure speculation/extraction/Rentierism.

As the comment you replied to wrote:

"The problem is largely in the system of exchange we call “money,” and in the banks that store and distribute it. Rather than allowing the free exchange of labor and materials for production, our system of banking and credit has acted as a tourniquet on production and a parasite draining resources away.

Genuine economic freedom requires that credit flow freely for productive use. But today, a handful of giant banks diverts that flow into an exponentially-growing self-feeding pool of digital profits for themselves. In the wake of the 2008 financial crisis, much of the global economy has been battling economic downturn, with rampant unemployment, government funding problems, and harsh austerity measures imposed on the people. Meanwhile, the banks that caused this devastation have been bailed out at government expense and continue to thrive at the public trough. All this has caused irate citizens to rise up against the banks, particularly the large international banks. But for better or worse, we cannot do without the functions they perform; and one of these is the creation of “money” in the form of credit when banks make loans.

This advance of bank credit has taken the form of “fractional reserve” lending, which has been heavily criticized. Yet historically, it is this sort of credit created out of nothing on the books of banks that has allowed the wheels of industry to turn. Employers need credit at each stage of production before they have finished products that can be sold on the market, and banks need to be able to create credit as needed to respond to this demand. Without the advance of credit, there will be no products or services to sell; and without products to sell, workers and suppliers cannot get paid.

If banks have an unfair edge in this game, it is because they have managed to get private control of the credit spigots. They use this control not to serve business, industry, and society’s needs but for their private advantage. They can turn credit on and off at will, direct it to their cronies, or use it for their own speculative ventures; and they collect the interest as middlemen. This is not just a modest service fee. Interest has been calculated to compose a third of everything we buy."[1]

The strongest alternative I am seeing emerge at this point is a new distributed peer to peer cryptographically secured accounting framework/pattern called Holochain. It allows us to rapidly prototype, and start using, new types of mutually sovereign asset backed Mutual Credit 'currencies' [2] (wealth-acknowledgement systems), based on productive capacity and measuring this wealth in new ways that isn't possible to integrate with today's money system. This includes the use of reputation currencies (think FairTrade labels, Organic veggie labels etc.). Building on this are projects like http://valueflo.ws.
