You're missing the point. The difference between three-year-old and fifteen-year-old whisky is mainly due to capital costs, not labour costs. According to the LVT, capital costs are not real.

Capital costs are not real in LTV?
A carpenter takes wood, nails and hammer and creates value making tables.
Hammers are a capital cost and are made the same way - workers are a factory xreate value by assembling steel and other components making a hammer.
Steel workers un a steel mill create value by turning iron into steel.
Iron miners create wealth by mining iron.
And so on.
Capital costs are accounted for. Not turtles all the way down, but labor - newly created value comes from labor. The value in a hammer comes from the labor to make it a year ago when you bought it.
