IMO the author is right: truly anonymous publishing is an unattainable goal for most people today, because they have little choice but to rely on one or more third parties to obtain all the layers of hardware and software necessary to publish online, and such third parties either cannot fully protect or ensure the protection of their anonymity or (more commonly) need to know the identity of their customers.
However, I disagree with the author about the impossibility of buying bitcoins anonymously. Bitcoins can be purchased anonymously via local dealers and over-the-counter venues. One sends cash along with a Bitcoin address; one gets bitcoins delivered to an address in the blockchain in return.
If you're willing to wait and are willing to throw down some initial capital you can also mine bitcoins directly. Freshly mined bitcoins are difficult to impossible to trace (not even to the machine that mined them) (with small variation in anonymity depending on whether you mine using a pool, and I think whether you can assume that your enemy doesn't control the vast majority of bitcoin miners).
Yeah; that was my first thought when the OP wanted to obtain bitcoins anonymously. Of course, getting access to compute power is probably easier for me than for most people, but eh, even so, it seems like the easiest way to go.
