A question: When stock owners die, what happens to the stock? I thought I heard it went back to the owner or the company but could it instead be put on the NPC Market? (it's part suggestion past question I know, but before I suggest the idea I though I'd find out what happens at the moment.)
Right now, it goes back to the company itself, yes. Your other question would belong in the suggestions forum, but would not likely be well-received. A "stock market" is being planned, but it is separate from the NPC Market.
I like the idea. Regardless of whether the bonds are actual items or not. I'm sure they could be tracked electronically. This would be a good way for governments to increase their capital. I know some governments have all they need, but others don't.
