Once again, the point is that money is not the problem, humanity is.
Then change the topic title or make this more clear.You can not change instincts, at least not with our current technology, so what do you propose we do to fix this? Getting rid of money (which is what you are saying, or did say) will not get rid of the problem
Even if we replace our currency with something tangible, as you said, humanity is the problem. Whenever there is large demand and short supply, there will be trouble. Whenever you have large groups of people spread out across the world, there will be groups with different interests and that will lead to trouble.
Personally I'm glad we have money, I doubt we'd have the technology we have today without it. Without it, we wouldn't be able to even talk about this. We'd be living in our own separate communities and have less chance of interacting with people across the globe.
Money is a motive. Imagine a world without money; no-one would be motivated to do anything.
You're forgetting about the will to live, which will motivate more things (possibly creation of more money).
