Regalian roles are to ensure fair competition by reducing any actor bigger than the state to something smaller, and ensuring the economy works with transparent information (no lying, rule of law, etc.)

Companies getting too big are natural; Letting them get too big is what happens when your state borrows a trillion per semester: Your state is obese, intervening in every little sector of the economy (thus the opposite of liberal), and not playing its regalian role.

You should indeed reduce the size of both the state and the largest companies, to let the economy self-regulate, but then, how would the US govern the rest of the world?
