Many actions have a negative value. If I give two toddlers ball-peen hammers, release them into a window store, and then close the front door while I wait in the parking lot, was my action likely to create value or likely to destroy value?
The fallacy is to think value was created by buying someone's labour to fix the window. This is value that's been displaced from something productive to something unproductive.
Instead of going from 0 to 1 (invest the money and create value), you went from -1 to 0 (spend money to fix the window to get back to where you were) and, overall, the value of a perfectly good window got lost.
