You said "value" of labor, not salary. Salary indicates at best, market rate, but often not even that. Value is something else entirely, and that something seems to be completely disconnected from capitalist measures of market price. See: investment banker salaries vs teachers. See also: the price of a monkey JPEG. Even capitalist value is disconnected from market price, see the current stock market.

Anarchists in Spain did in 1936 when they syndicalized the majority of the economy. BTW Walter I'm not sure you remember but I'm fairly certain you've replied these exact words to me before.
Value is what you're willing to pay for something, and what you're willing to accept as payment.
> Even capitalist value is disconnected from market price, see the current stock market.
The value of a stock is the market price. There is no other value.
The value of a teacher is what you're willing to pay for him, and what he is willing to accept. The value of government paid teachers is not knowable, since the money to pay them is forcibly extracted.

Your confidence doesn't mean you're right. Your definition of value doesn't include a mechanism to determine the difference between contextual value, an awkwardness obvious in your comment, after all, the stock market wouldn't exist unless the value for a seller was different than the value for a buyer, or why else would the buyer buy? There's more than just price involved in the consideration.
Also, the word "value" is used outside of monetary contexts. If you said "I value you" to a loved one, I doubt even an avout capitalist libertarian such as yourself would be so heartless as to put a dollar price on that "value." So no, value is not just "what you're willing to pay." That's a Chicago school of economics lie that has been allowed to determine the mechanics of neoliberal society.
In any case this isn't really a conversation if you just keep saying the same thing over and over again, "value is cost," using basically undifferentiated examples.
Me too, but it's impossible to do so in any meaningfully accurate, objective, measurable way.
