Question 66: Why does Marx write in 127:1 “the valid exchange-values,” instead of simply “the exchange-values”?

[35] AJoseph: Valid exchange-values.   By writing there is “equal content” in the exchange, Marx is re-affirming its validity, when many exchanges can be dubious in nature. ZACH's [28] is a good example, because lumber is something people really need.
