A company will grow up to the point the market needs it to grow. In a pure capitalist market without government I would expect to see a few large players where replicating the technology is really hard and then a bunch of large companies being killed by newer competitors. We kind of see these mechanics in our market but nowhere close to enough. The distortion in our model of crony capitalism is that our centralised government gives unfair advantage to existing corporations in the form of bailouts (hey, too big to fail!) and regulations (easy to implement when you're Amazon, a business killer when you're small). I would love to build a fintech startup and do what banks are doing for cheaper, but regulations in the banking sector make it a very expensive endeavour. Anti trust is not the solution, it's merely a small patch which gets applied incoherently and used as a weapon by governments to steal more money from massive companies. I argue that no regulations would have a better effect on disrupting large monopolies, once there is enough money to be made with little risk.
