Also it seems like some people come up with absolutely ridiculous points when it's explaining a system they're not used to. The thing about trades being for like-value and saying "but if we did that nobody would ever gain anything and nothing would ever be created!" is really, absolutely ridiculous.
We trade like-value for like-value now. That's what trade is, it only occurs when both sides believe they're getting fair value. Saying that because it's between worker-owned organizations then suddenly this basic fact of trade won't apply anymore, therefore nothing would ever get created in such a scenario. It's a very, very silly argument, and clearly is a red herring.
When you make something, whether that's crafting or by digging up that iron ore I mentioned, the value is the labor value, and you can then exchange that for something of equal labor value. But that doesn't mean "nothing can be created". You embed the labor value into the object or service by expending the required labor. That's where the value is coming from, and that's why there's no issue with "creating value" in that scenario.
Trade, by itself, never creates anything. Even if one side gets less than the other, the amount of total value cannot change via trade. Therefore it doesn't matter whether trades are for equal-value or not, that has nothing to do with how value is created in the first place. The value is that if you make something that took 1 hour to create, then you can trade that to someone else for something of equal value (equal amount of time investment). So, under that scenario you will get richer to the tune of 8 labor-hour-values, per day. You're not going to get richer any faster than that in a capitalist system, unless you're skimming off the top of someone else's labor, and thus depriving them of their full 8 hours of value.
