I like most of the ideas here. The biggest things that stick out to me are in trading. I like that you are forcing trades to be done in one place, rather than being able to somehow send items anywhere at any time. However, I believe disabling the dropping of items would be silly. Imagine you're in a business, and you want to drop some minerals to some stockers or something. Yes, you could go through some storage bin or something, but I think it'd be much more beneficial to simply leave the drop trade as-is.

EDIT: Perhaps disable dropping of guns.
