Aren’t there always three pieces though? There is 1. Coming up with an idea, 2. Organizing the capital and labor to realize the idea, and 3. The labor to build the thing. Sometimes, that is all one person, but all three pieces are necessary.
This question seems to misunderstand the topic. The assumption here is not that there is no labor involves, but rather that it its amount is not what determines the value of something it's been put towards.
You misunderstood my answer. I wanted to show that labour is the foundation of all value.
Weather this labour gets payed equally to the trade value is a follow up question, not tackled by your wikipedia link either but very important to discuss accumulation of capital.
And i was really interested in finding some value independent from labour.
