Money is not the point. The idea of money is just for the reason of simplicity. If I am a sheperd and you are a carpenter and I need a table and you need a lamb, we will swap, right? So, to avoid me carying the lamb and you carying the table all the time with you, there should be some kind of voucher that will guarantee the value of the goods in exchange. As everything in human kind it has been twisted to the point of absurdity, so now money does not represent value behind it, but is it's own purpose. The only true token of value of human creation should be WORD or PROMISE as such, that I will provide you with service or goods in exchange for your goods or services. But people are not honest, so that is reason why we have to have money.
Yes, money become total absurdity. Perfect tool for enslavement. "But people are not honest"...in the end changing monetary system won't change anything because it's all illusion. Only thing that can change the world is we to become honest. Then we won't need money or anything else. We could use money even then, but it wouldn't be like right now.
It's not about money system in the end, it's about people in the end.
The problem is monetary system as is today is perfect for creating enslavement. Even I think we should organize society without money, don't see anything bad about money in the end. But monetary system can be optimized for manipulations and because of it we should organize things other way. Long long story for many articles. I will write few of them fir sure.
