I agree with that... like on the one hand I can understand why findom exists, and I would never yuck anyone's yum...but on the other hand, in my experiences it seems so foreign or counter-intuitive to my understanding of Dom/Sub dynamics.
Counter to what folks believe, submissives are typically in the most control in a DS relationship. A true Dom only enforces the boundaries and restrictions that a sub relinquished to them. But it is in the doms best interest to "care" for their submissive.
I've no experiences with findom, but it just reeks of exploitation and capitalistic greed. No real give and take, just a one-sided transaction. (Of course I could be 1000% wrong)
Where is the subspace (feelings of euphoria and safety/security) in findom? Where is the aftercare? I sincerely doubt the Dom in these situations gives back the money/gifts/ etc.
