Boy, the logic in this article is bad.

PoW is not the only solution to the BFT. PBFT PoS, DPoS, etc are all "solutions", in that they represent a series of tradeoffs to achieve consensus in the presence of faults, just as PoW does.

Further, PoW itself as implemented in large part today is vulnerable to attack via selfish mining.

Finally, purely empirically speaking, PoW in most systems like Bitcoin today is highly centralized and far from trustless. Consensus authority has accumulated in the hands of large mining operations. Many people foresaw this outcome. In the author's analogy, you are not provided any certainty of consensus on your bunker, rather, massively resourced authorities controlled by a handful of people are dictating state to you and you have nowhere near enough resources to change that.
