I disagree with this. Learning the Dust Release appears to take a significant amount of time, even with mastery of chakra flow. Furthermore, the most significant user in canon, Onoki, learned it from Muu. Additionally, there are two things we can assume: Muu created it/was the first to awaken it, or learned from the First Tsuchikage...which also would be a possible criteria for the Tsuchikage title. Nevertheless, learning the Dust Release from a third party doesn't seem exactly reasonable, even if one has all three natures, again from what I interpret in canon.
