To be fair to the previous commenter, they did not explicitly propose cryptocurrency as a solution; they're just asking a question. Also, cryptocurrency != blockchain technology.
That said, I do agree with your sentiment that the blockchain-as-a-solution space is getting a bit ridiculous. I can't imagine a way to translate this problem into a smart-contract-solvable form.
