So make the containers level acessible... Example: Level 40 + Can open them.
Possible, but probably not something they considered with all the other stuff they had to do for release. I'm sure they'll patch it in, but in the meantime, rules are rules.
So if players what to spend all day farming credits for their own use they can be warned or banned? That doesn't seem right and runs contrary to maintaining an open economy.
If you want an inflated and broken economy, sure. Just look at WoW, even low level items were being sold for 10x what they were actually worth, and it got progressively worse as time went on.
