Yeah, part of what I was intending in the scenario would be that everyone realizes that we could make much faster technological advances (At least, that's the theory) if we didn't bother with keeping track of who owes who. We need resources such as metals, we get them, make the MacGuffin, and continue.

I suppose the real problem with this is some form of a game-plan, determining who needs what. So I guess what I'm thinking is a system that would require some flawless AGI to determine what group needs what resource at what time, to further the general human endeavor, rather than people getting what they want/need based on how much money they can amass, which is as we know a flawed system, or people like Donald Trump would not exist, while people starve to death in Third-World countries.

But the idea would be to use some system like this to vastly accelerate our speed of technological advancement, so that we can colonize the galaxy, become immortal, and eventually figure out how the world works. However that's not to say that I'm trying to really come UP with a system, because I'm sure such systems are already postulated, but just don't work, because of the whole 'greed' thing, but yeah. My query was mainly whether there could be problems not in developing the system, but in actually enacting such a system, even if it worked as intended.
