monopolies are a snowball issue. working capital generates more capital at scale, and the easiest way to operate is to have control over all portions of your logistics chain. you start vertically expanding along the chain, and it isnt an enormous leap to start doing so horizontally. before you know it, you have the entire industry de facto under your umbrella. this is a quick road to an oligarchy, and anti-trust laws are there to prevent this from happening.
