I guess I just don't think that's a distinction worth making. The size of the ecosystem is what matters. The billions sitting in accounts denominated in that currency, and the daily total volume actually do matter, even if the trades are not mostly not happening on chain.
It matters if you want to draw a distinction between "payment processing system of the future" and "illegal casinos and gambling den", since these two should also be regulated somewhat differently. Evidence points to crypto being more akin to the second, and your comment also provides supporting evidence for that.
