Great analysis of the original author's points. Thank you for sharing a compassionate response as a critique. I'm learning a lot from you and bettering my online communication skills when dealing with people who may not have worked out their philosophies just yet (which is most of us, especially when we get emotional).
On the point of cryptocurrency, I just started learning about it in the past 5 days, and it is amazing what this technology (on a blockchain platform) can do for humanity. From my understanding, I see blockchain as a secure program that basically gets coded with the rules that all those who participate in the program consent to. So already, this is a voluntary platform that is near impossible to hack, and that is completely transparent to its users. That's already an extreme improvement over the current system of corrupt politicians and bankers.
Now currency, whether fiat or electronic, is basically money made out of thin air. It's all about the people's trust. It's just a number that we can agree on to exchange goods and services. Except fiat currency has no limit, creating inflation and deflation based on the manipulation of those who are in charge.
Cryptocurrency on the other hand, is closer to the system we had with gold, meaning it has been programmed to act like a tangible resource that holds value, eliminating the entire inflation issue. It is still made out of "thin air" in a sense, but it remains a step above bartering. Once people start using it and believing in it's purpose of exchanging value without a middleman, it will actually revolutionize our entire economic system.
I think we have been taught to understand what money is the wrong way and it is hard for many people to accept that it is truly nothing but a number (because the Fed has been controlling all of us with it making us rely on it heavily for survival).
Please correct me if I misunderstood anything.
