I disagree with that idea (banning ores from POBs). Why? POBs, like Shuri, is a perfect idea for two groups of the people: miners and shippers. Miners fill Shuri, being paid 3000(?) per He-3 unit - WHICH is the price for shippers, an investment, that however triples theirs income (9000) delivered to proper place. In short: want more money, mine it or invest some credits into that.
That's the best form of economy I've seen on Disco, being pretty close to real life, albeit simplified. Miners deliver ores to POBs, where these are "refined" and shipped by different entities - be it foreign importers or domestic exporters.
