I believe I have discovered a new way to deal with parasites. Steal from the looter. Always demand from the parasite that you need to meet the producer and hear it directly from them the nature of the values to be exchanged. Once you meet the producer, make an absurd demand and break-off from the deal. Then make a parallel offer to trade directly with the producer instead of through the parasite who seeks unearned benefits. If it is the case that the market maker is not a parasite and only seeks the benefits it deserves. Then deal through the market maker.
