He is stressing the significance of the states acting to secure their interests and prevent the growth of monopolies. He is also cautioning that if the states do not do something about it, they will ultimately discover themselves in a situation where their interests are no longer in their own hands. This quote serves as a pointer of the value of the states taking action to protect their interests and avoid the growth of monopolies.
