Did you read the article?
Quoting: "In 2014 a large school of thought suggested that the main breakthrough use case for Bitcoin would be peer to peer transactions. That being customers and businesses paying for goods and services directly between one another without having to rely on payment networks such as Visa."
The use case is certainly for consumers. Direct consumers. Same with Linux Desktop. Just go to Ubuntu.com - what are they pitching?
In my view, there is no question whether there is a lack of user focus. It is one of the major reasons (if not the top reason) for lack of traction.
We already have cash for that! It completely ignores the reasons why people use payment networks like Visa instead of just exchanging cash. There are fraud protections, credit, reward points, etc. What bitcoin brings to the table is simply not something very many people actually want for the tradeoffs involved.
See, neither of these things can be presented to a user as a tool that can make their lives better, which is what users actually want. Strip away all the hype and math and crypto jargon and what is Bitcoin to someone? An inconvenient currency they can't pay taxes with and have to jump through hoops to use for nebulous benefit. Where did Bitcoin actually find traction amongst users? As a way of transferring money overseas, because it could do it with a lot less hassle than traditional methods.
