Wow. Ok, next time you go to buy groceries, please try trading some of your goods for them. Oh wait, you have no goods of value. Guess you can starve to death. See why this super fake "money" stuff is so essential in modern society? Also, such an analysis of money fails to grasp the actual concept of the institution. Back when humans were exclusively hunters and gatherers, they would trade goods for other goods. However, as civilization grew, this manner of trading became increasingly inefficient, especially for some professions. For example, how is a blacksmith going to obtain the raw materials for his craft in addition to purchasing food? He could trade swords and other such products for iron, but then he couldn't eat. He could also trade his works for food, but then where would he get his raw materials? This is when currency came into play. People would use gold (the value of which was "fixed") as a substitute for actual goods. Now, the blacksmith could buy his raw materials with gold, create an item, and sell it for more gold than he invested in the materials. He could then reinvest some of that gold into more materials, AND buy food, whereas previously, he would have to chose between food and materials. Gold was, in this manner, very transferable. It could be used to purchase anything, whereas goods may only fetch certain other goods in a trade. This allowed for the compartmentalization of labor, which allowed civilizations to grow (not everyone needed to farm food for themselves, so other professions sprung up, leading to increases in technology, etc). Eventually, it became inefficient to carry gold around, so currency was invented to represent a certain value in gold. In fact, this is how the USD works: the value of the USD is DIRECTLY related to the value of gold in Fort Knox, and other such banks in the treasury department. That's where the term "gold standard" comes from, as gold is the literal gold standard for the value of any good, service, or purchasable entity in our economy (this is true for many modern nations). So when you say shit like
"real life" currency is also just a fictional thing made up
You couldn't be more incorrect, as "real currency" has its worth defined by the current value of gold.
IP, however, has ABSOLUTELY NOTHING to back up its value. There is no "gold standard" for IP. It is worthless outside of League of Legends, it is completely nontransferable, and to say otherwise is categorically wrong.
