A blockchain is relevant in cases where there needs to be an actual chain. But in any case, you're focusing too narrowly here. Instead of honing in to try to disprove that a given technology is the proper solution, it's smarter to try to understand what happens when such a solution is widely deployed, and what pre-conditions are present today to help predict if, when, and how it will happen. Regardless, Bitcoin-like blockchains are already dated technology even within the cryptocurrency space.
