Why does this sub think that the LoF give away treasure?

In the Dialogue Taash has with Bellara, they say that the Lords have a Dalish Keeper who they let appraise anything that looks Elvhen. If it is Elvhen, they then let him have first dibs at buying it, so that the treasure is with people who will appreciate it. He's not just a consultant, he's a buyer. Yet it feels like everyone on this sub thinks that the Lords just him the treasure for free.

You do realize that someone to whom a treasure has a lot of cultural significance would be willing to pay a LOT for said treasure, right? And sure, a Dalish Keeper can't pay a lot in coin directly, but he could trade using Dalish positions, crafts, gear, etc. that the Lords can then use or resell for gold.
