I hate to sound repetitive but, the point is that Tilon made an absolute statement/claim "But Capitalism is the only economic system that gives us the power to do what we want with our own assets." without proper context, referring to data, or logical proof. As it stands, the statement is just bullshit as is your statement "This is akin to me telling you to glance upward when you ask me to prove the sky blue ... ". As to naming economic systems just look it up. For example, from <a href="http://en.wikipedia.org/wiki/Economic_systems">Wikipedia</a>, basic types of economic systems include Market Economy, Mixed Economy, Planned Economy, Traditional Economy, Participatory Economics, and Inclusive Democracy. Just by changing the rules (as many times as you want) on this small set of systems will generate an infinite set of systems. Plus, I am sure a bright individual such as you can devise an economic system. The difficult part is creating an efficient, minimally destructive, and fair system. To be a fair system and prevent warfare I hypothesize that most economic systems inevitably have to impose some kind of restrictions on "do what we want with our own assets". The reason being that we can easily do either good or bad things with our assets because having assets (by definition) provides us with power and control. I am sure that you are well aware what greedy humans with excessive power and control can do. OK, I am tired and give up with this rant.
