This is a fair point, but from my reading of the OP it doesn't sound like they're asking the EXP rewards to scale to market value (which would be difficult to do outside of having an algorithm tie it directly to recent sales) so much as noting that trading in items incurs costs - both actual gil cost if you're buying mats, and opportunity cost from not selling the finished product. A rational player, when presented with two options that impose similar costs, will choose the option that maximizes their return, and at the moment that's leves.

Though it would be interesting to factor in the fact that collectables are untradable when figuring out the opportunity cost. Leve items, particularly HQ ones, have demand pressure from the fact that people can buy the finished products and turn them in, while the same isn't true of collectables.
