Credit cards, direct payment or other methods work well and cost the consumer nothing. Therefore I do not see why the average consumer will want to use it. If they do not see a compelling reason to adopt it then no retailer will.
Here lies the entire premise of his argument that consumers do not see any significant benefits; therefore, retailers won't use it.
But I do not agree with that. Bitcoins provide significant benefits to retailers and some will adopt it just because of those benefits.
Philip Rooke seems to equate consumers to e-commerce.
While, in reality, e-commerce has a second, equally significant part - merchants.
Currently merchants are being "dominated" by the system, while consumers are being babied and protected.
I believe, it will be merchants who will drive the Bitcoin adaptation.
If Bitcoin becomes as easy to use as Paypal, it will be be adopted by consumers.
P.S. I agree with his points that, from the consumer point of view, Bitcoin is a "pain-in-the-ass" to use.
And it would seem there are really no benefits, but just drawbacks to using it.
