FW LP is one of the most valuable commodities in the game. For example T2 production, faction ammo, navy ships and most implants are tied to them. However they are not tradable on the open the market.
This inefficiency increases the likelyhood of shortages and price spikes on those items. Is this desired?
A related issue is the distance to stores from trading hubs. For example the Caldari FW LP store which seems to be the one in highest demand is close to Jita and far from Amarr for example. This seems to contributes to trade centralization in Jita.
