The person I replied to literally said "the rest by bartering or agreement". I guess you could stir money is an agreement but that's not what I took from their message
Also how are you going to solve the scenario I provided?
I don't understand how that's going to solve the scenario I described.
There's stuff I can do but don't want to. There's stuff I would do in exchange for something. But once that "something" isn't what you have, the reasons for currency become apparent.
So if someone asks me to do a thing for them, I can only do it when working in an official professional capacity, or through unofficial favor exchanges?
Because I don't want anything you have, but trying to build a whole barter chain where we trade everything in sequence until everyone gets something they want is wildly impractical. As described in my first example.
And yes, today I pay a dude money and he does the thing. I don't have to clean his gutters so he'll agree to knit me a sweater.
