Due to the "universal union" that nations have with their populace, List stated that "from this political union originates their commercial union, and it is in consequence of the perpetual peace thus maintained that commercial union has become so beneficial to them. ... The result of a general free trade would not be a universal republic, but, on the contrary, a universal subjection of the less advanced nations to the predominant manufacturing, commercial and naval power, is a conclusion for which the reasons are very strong. ... A universal republic ... , i.e. a union of the nations of the earth whereby they recognise the same conditions of right among themselves and renounce self-redress, can only be realised if a large number of nationalities attain to as nearly the same degree as possible of industry and civilisation, political cultivation and power. Only with the gradual formation of this union can free trade be developed; only as a result of this union can it confer on all nations the same great advantages which are now experienced by those provinces and states which are politically united. The system of protection, inasmuch as it forms the only means of placing those nations which are far behind in civilisation on equal terms with the one predominating nation, appears to be the most efficient means of furthering the final union of nations, and hence also of promoting true freedom of trade."
