Adoxa cracked this to an extent, for single player at least.
Even if this could be implemented flawlessly for Discovery, it's quite a clear and obvious no. Efficient and completely afk (barring combat, of course - which would not count as a sufficient detriment in the long run) trading would bloat the economy to a ridiculous level. Quick and near-effortless trading is fine for the balance of some games, but terrible for most; Discovery falls squarely in the latter category.
