> or references to sentimental value (such as the subjective value of artwork, collectibles, and other objects) as though that invalidates the ltvs applicability to ordinary consumer products  it does because how much someone subjectively values something determines its market value. for example, i like to eat potatoes more than carrots but someone else might be the opposite. how do you determine how many potatoes or carrots to produce if they are price controlled based on the labor it took to make them?  > labor theory of value is also consistent with supply and demand - that is, market forces that determine the money prices of objects, because it is trivially obvious for example that the easier something is to make on your own, the less demand there would be for such a product  what about something that takes $100 worth of labor to produce? how do you determine how much to produce?  command economies do not work. you are not some genius who's finally cracked the code and figured out how to beat the free market.
