How can you debunk this? The usual point is that I read from Marx is that if you for example sell something for more than its value that if everything was based on that he would loose that what he won because the initial things he bought, theyd do the same. Is there something else to argue against this?

And when people ask "give me evidence that value exists", which is the for the reproduction of a product societal average needed labor time, what would I tell them? Whats the evidence?
