So often in life - you can watch for free. Some people even give out free samples for free - samples of food, free test rides of cars, etc. Of course, the dollar is the best thing because it can be converted into many other things very fast - what a nice currency. Have you ever tried to sell gold or other precious metals? Not so easy - it will not sell if they got rust, stains and filth on it.
