This is how you came to your conclusion -No breh... it really really really doesn't... at all.
I dont know how to explain this to you, so just trust me.
"If any you are having trouble understanding this, think of it this way:
"-One person steals from $100 from the store, runs away, and is never seen ever again
-Someone else buys something in a store for an arbitrary amount of money
How much money is lost?"
The problem with this is the person who stole the money is actually buying $70 worth of goods and getting $30 in change, your reasoning would only make sense if that person who stole never returned AND someone else went into the store and used $100 to buy $70 worth of goods + $30 in exchange. It's not the person themselves or the bill itself (because we're clearly talking about the money the owner lost), but the amount he lost after both the incidents.
