>>4397176Lets see
Owner starts with 100$ (future goods) and 70 in (current goods)
Robber starts with nothing
Robber takes 100$ (fg)
-100 owner
Robber exchanges stolen (fg) for goods
70 dollars worth
Owner gains 70 in (fg) and loses 70 in goods nothing is the net so owner still losing 100 value
30 dollars is returned to robber
Thus owner loses 100 in value
But lets be honest though the whole economy probably lost something cause the robber probably bought drugs when i couldve been used elsewhere.
