I've come across two interesting bitcoin skeptic articles today.
First brought up something called the governance paradox: a payment system needs a way to enforce rules, and (possibly even more important) a way to make them, bitcoin only really has the first. Because of the anti-establishment ideals on which it was founded, it's governance is a bit random. The paradox is that if there were a trusted institution making the rules, they could enforce them, and you'd no longer need the blockchain. (Though I think I have an answer to this: use blockchain to implement a voting system that elects a board of directors to make the rules...)
The second one is actually saying blockchain isn't of much use, so it's not just an attack on bitcoin. (Although I'm a bitcoin skeptic I think I can see some uses for blockchain.)

Some quotes:-
In the end, the advantages of the existing human and software systems surrounding transactions — from verifying identity with a driver’s license to calling and clarifying the statements made in a credit disputed transaction to automatically billing your credit card for a newspaper subscription — outweigh the purported benefits, as well as hidden costs, of irrevocable, automated execution. Blockchain enthusiasts often act as if the hard part is getting money from A to B or keeping a record of what happened. In each case, moving money and recording the transaction is actually the cheap, easy, highly-automated part of a much more complex system.

In conversations with bitcoin entrepreneurs and investors and consultants, there was often a lack of knowledge or even interest in how the jobs were being done today or what the value to the end user was. With all the money spent on bitcoin cash registers, nobody went out and did a survey about whether most credit card users would be willing to give up their frequent flyer miles in return for also losing the ability to dispute a transaction. Presumably, they thought, the reason IPOs are so expensive or venture fund formation paperwork is so onerous is because all those lawyers and accountants are just getting rich sitting around pushing paper… a bunch of smart engineers in their 20s with no industry experience could certainly do their jobs, automatically, in a matter of months, with just a few million bucks of venture capital.
