This is a very poorly expressed argument. Even if we suppose that everything you’ve said is true, the existence of a second plausible explanation doesn’t invalidate the first. You’ve not actually any reason why any of what I said is wrong, you just said “X is possible, therefore Y cannot be true.”

Also, I want to note that this particular digression wasn’t about cryptocurrency at all. The point I was responding to was a claim that blockchains had uses other than as currencies. So you really might want to step back a bit and consider what you think is being discussed here, and what you’re actually trying to say.
