" Art - A skill at doing a specified thing, typically one acquired through practice" !
First it was the exchange of goods.
After they found the gold, you can't eat it, but it doesn't rust.
After that, another metal.
After, a cheaper metal and they start to produce coins, insert a number on that coin, symbolizing the weight.
Made more coins, with more numbers, symbolizing something.
Made bills, a paper with some amount of metal inserted, and a number.
More bills, but now just a piece of paper with fititious number.
Now we have numbers, virtual ones.
(So, money is the perfect form of art, the art of maneuvering an illusion trought practice)!
I'm selling this one for one trillion euros if you want it !
