From wikipedia:
Contrary to popular conception, there is no evidence that societies relied only on barter before using money for trade.[73] Instead, non-monetary societies operated primarily along the principles of gift economics, and in more complex economies, on debt.[74][75][76] When barter occurred, it was usually between strangers or would-be enemies.[77]
You may be surprised to know that not everybody grows up in a nice family. You further be surprised to find out that some parents have children so that they can be taken care of later in life - I take care of you, you take care of me. There are children paying rent to their parents right this moment.
The further away the relationship, the more quid pro quo comes into play. The fact that there are some people who do not require some kind of compensation (love, hugs, material good, money, …) for some actions, doesn’t mean that won’t require it for others. People can have unconditional love for another person and still demand payment or compensation from another.
This thread is specifically about one of the lies in question. And I gave another example. You don’t seem to be arguing that those lies aren’t indeed lies, so if I’m understanding your arguments correctly, what you’re trying to get at is that neither “barter was a thing before money” and “homesteading is a thing that actually happens/happened” are “foundational” to pro-capitalist thought and “the foundation” of capitalist ideology is instead something along the lines that “quid pro quo and keeping score are human nature and money is just an abstraction thereof”. Yes?
I’m saying that I find the existence of counterexamples (as well as the whole “gift economies were the norm before money” thing, and that capitalism has existed for a great minority of the time anatomically-modern humans have been around) a compelling reason to be skeptical of that stance.
