I explained basic economics to you
No, you've just been shilling for an interest-based debt system, while arguing that it's advantage comes from "providing opportunity."
You've just said that money has intrinsic value by government fiat under the threat of force. This is fundamentally and technically wrong, though it is what's happening in the current system and people have little choice but to accept it, unfortunately. Money is literally a "promissory note," which is just a fancy way of saying it's a universal IOU. The IOU itself has zero value, it's just a fucking piece of paper with a number on it. It's value comes from being backed by something with real, intrinsic value, like a natural resource that has utility. If you have nothing real to back your currency, you effectively have Monopoly play money with fancy counter-fraud measures built into it - and maybe some shiny, cool-looking holograms.
If you want to test an idea, you have to challenge it against edge-cases, asymptotic cases, and other extreme cases. If everyone in the current economic banking system decided to cash in their promissory notes to the government and asked for something like gold, silver, platinum, or other valuable resource, the entire system would collapse in a day and you'd have a huge percentage of people holding worthless notes (which they already do, but don't quite realize yet). The current system is an artificial house of cards designed to grow like a cancer, or eventually collapse one day under its own weight and leave vast swaths of people completely fucked. What are you going to do then, press a button and start printing a new kind of money?
Take a recent historical example to illustrate this fact of the fragility of this kind of system in use. Gaddaffi wanted to unite the African nations to do exactly this: demand resources in exchange for their countries' natural resources, namely gold. This would have toppled the house of cards practically overnight and destroyed dozens of national economies, especially in Europe, because there quite simply isn't enough resources to pay those African nations in exchange for their oil (with Libya having the most) to keep up with the demands of their national economies back home. Because they couldn't let their fraudulent system be exposed and collapse, thus losing much of their control over their own countries, the "powers that be" pursued an aggressive campaign against him, full of propaganda, mercenaries (sorry, "contractors") to train a rebel insurgency with supplied weapons, and manufactured public support against him. They swiftly and ruthlessly deposed and killed him to protect their corrupt system.
And nobody even fucking remembers or cares what happened.
Are you your family members bankers, by any chance, or have you simply drunk too much of the Kool-Aid they fed you in university? Why do I even bother asking, you don't answer these types of questions anyway.
