The problems that the creator describes are all correct, as we know.
However, simply recognizing the problem and trying to circumvent it, doesn't necessarily create a good solution.
I think there's a difference between bashing and criticizing something based on facts and good reasoning.
I think Bitcoin is just one terrible thing and it will become obvious in the future. I just want to prevent people from making a big mistake.
But of course, everyone can make his own mind about it. I think there is no necessity to agree on Bitcoin in order to agree on liberty.
