The comment about was about as far away as you can get from supporting the “blockchain not bitcoin” argument. It was “not only is bitcoin the only one that matters, but it would still be the only one that mattered even if designed differently”.
I believe that there is a lot of economic theory that went into bitcoins design but there are many ideologies within economics. Economics is far from a hard science and the fact that bitcoin is the way it is doesn’t necessarily mean that’s the only way it would have worked.
That said, I do think the scarcity narrative has helped bitcoin adoption from a game theoretic standpoint. Just wondering if we will se unforeseen consequences of those choices down the road.
