It's a good interview. I don't think Identabit will scale well because the big doors will be locked, also on the technology side they will have nothing that can't be replicated and they don't have the super massive funding that's required to compete with the likes of Blythe Masters and such ('It's on the blockhain' - Bloomberg Magazines Cover story 2 days ago

In his intro John identifies how a key difference between crypto and current payment options is convenience and simplicity however I would argue the simplicity, convenience & payment integration of crypto is only starting to take shape. With 1 second vs. 30 minute confirmation times. Crypto-funded debit cards, payment apps & stable BitAssets only starting to be introduced. I think it is too early to make his judgement.
Also he makes some statements about Bitcoin use and demographics that I don't think are backed up by the facts.
The vast majority of Bitcoiners were young tech savvy Libertarian males not a small group of elites only using it for extremely illicit activity & as Bitcoin becomes more user friendly this demographic is naturally becoming less tech savvy and from a broader political spectrum attracted by the various now more accessible benefits Bitcoin provides.
25 Sept 2014 -
http://www.bloomberg.com/news/articles/2014-09-25/bitcoin-economy-widens-as-parents-pay-digital-allowancePeople worldwide have opened 41 million bitcoin accounts, according to the Bank of England. Global spending on goods and services has doubled in the past year.
Parents are dispensing allowances in bitcoins so their kids learn to be digital citizens.Consumers in emerging markets such as Brazil and Russia are starting to use bitcoin to hedge against currency volatility.
Three factors are attracting consumers to bitcoin. The currency is less volatile. New apps and digital wallets make using it easier. And mainstream companies -- more than 75,000, according to payment services Coinbase and BitPay -- accept the virtual currency
Even if you were to focus exclusively on crypto's black market use. The black market accounts for over 23% of global GDP and in countries such as Greece it's pushing 25-30%.
Bitcoin ATMs could spring up across Greece as soon as October as citizens and businesses become increasingly desperate to move their money despite capital controls.
http://www.cnbc.com/2015/08/19/greece-could-soon-get-1000-bitcoin-atms.htmlThat is a massive portion of the economy and population already operating outside the reach of traditional institutions.
The reason crypto-currencies not owned by the big banks have the potential to be massively profitable & scalable is precisely because the traditional institutions are largely excluded from directly participating in it. I also think it's possible to integrate social media accounts onto crypto blockchains for the less privacy concerned users and so still gain certain network effect benefits..
I think Bitcoin has struggled in price because of the high costs which he identified but also the volatility which means the massive increase in use of Bitcoin by consumers for traditional goods and services creates a net downward pressure on price because businesses operating on extremely tight margins have to exchange BTC revenue immediately for fiat. However despite it's volatility, Bitcoin is very popular fro currency hedging vs. rapidly depreciating currencies in South America as indicated in the article above . Also in places like Greece as a safe haven currency outside their failing banking system.
However stable Smartcoins are much better suited to this and BitUSD is in many instances far more useful than fiat USD. So we haven't even scratched the surface of what's possible in these markets.
Also this is a global trend. Governments in many countries will be instigating strict capital controls to protect their currencies and their financial system.
(China just increased capital controls yesterday.) As a result I suspect, even with the Identity element most financial institutions would be not be allowed to interact with Identabit anyway. Or the Identabit gateways would have to enforce these restrictions too in which case Identabit would lose it's USP to the majority of the future mainstream market imo. (An inflation hedge and currency outside the over-leveraged banking system.)
So while I see a market for Identabit especially in remittances if they already have a partnership with a bank and can thus remove a layer of transaction complexity. I think centralised blockchains started by big players will dominate. (Centralised blockchains will likely dominate his target market because it seems unlikely that people who didn't value the benefits of optional anonymity & financial freedom would then highly value the benefits/USP's of decentral vs. centralisation.) So I think that the really big future still lies with the traditional, anonymity optional crypto, but with much lower costs than Bitcoin and stable BitAssets.
Edit: On a side note the use of USD at black market rates in countries like Argentina, shows how an entire population, economy and businesses can get behind using a currency outside of institutions and regulatory compliance
