The baker has 13 digital loaves of bread and a market of 100 buyers.
The baker begins copying the loaves and distributing them to the market, reaching a pricing point that gets all 100 buyers to buy his loaves.
You copy one loaf of bread and use it for personal consumption. Impact on the baker's market is minimal.
You copy one loaf of bread from the baker, but then begin copying more for distribution. 25 buyers who would have bought a loaf of bread from the baker then copy your copied loaf of bread. Impact to the baker's market is substantial. Baker is forced to close down. Potential new bakers are scared away from the market due to the ease with which to copy loaves of bread. Famine ensues. Wives weep, children go hungry. Everyone dies.
But seriously, your story leaves a lot out of the equation.
