You can disagree but its nonsensical to do so.Sorry but I disagree with you.
Gold/Loot are just mechanics to progress your power level. They actually don't even need Currency/Loot in ARPGs either. You could create the same effect with infinite scaling stat points-- the end result would be mechanically indifferent from gold or loot. Grind X to achieve Y.
That is the essence of an ARPG; the grind.
What you are grinding is of no consequence when the end result is power progression.
