Aurelian did some currency reforms, but he wasn't the only one who did so. "Right guy, wrong time" was meant more of a "He was great, but he was born in the wrong era"
Imagine an Aurelian after Severus Alexander, and not Maximinus Thrax! Alas, he came in to an Empire on the brink of collapse, expended his energy in reuniting the Empire, and then had the chaos and paranoia of the Crisis of the Third Century lead to his assassination.
But yes, we stan Aurelian in this house, Restitutor Orbis!
