I agree with this, yet boosting is rampart. So, if most players don't have enough gold to buy a boost, this also means that to get the gold required they're buying tokens.
It still means most of the gold is in the hands of few players (the ones that boost and ah flippers) while average joe either doesn't really do anything related to raid/m+ or buys a token to get a boost.
EDIT: however i also think that the actual "swipe the card to get ksm/curve/CE" is very limited. Most token transactions are from actual average players buying them to get gold at patch release to get their craft/consumables etc high as fast as possible. A sort of one time purchase to get a little boost (pun intended) at the beginning.
