I think you are right. But my argument was addressing the crypto-bullish assumption that crypto goes up (i.e., assuming long-term deflation) and that one should 'invest' in it as a responsible parent (as implied by the parent comment that I was responding to). So assuming a (potentially counterfactual) deflation was a strategy for my argument (like in a formal proof by contradiction).
