But those roads were already nonexistent, and their nonexistence is not affected by the existence of Coca Cola roads. In this hypothetical, we are comparing a world with no roads to a world with roads to deliver Coca Cola. Since some people like Coca Cola, I find the latter world preferable.
Should the bread company have to build their own roads, too? That's a better world, how exactly?
And what about the people who don't want to buy Coca Cola? Should they get to buy nothing?
