Before “nationalism” was used as a slur against patriotism, it meant quite explicitly, “centralized government.”

Uh, no.

Your response is not proof in the opposite.

One of those phrases in your reply, “it’s interests”, is where all of the big government centralization and collectivism is at. And TR, as many other nationalists, was not an individualist but he was a collectivist. In general there is no big “it” for individualism.

Two common refrains are a government takeover of the banks, and often times a government takeover of transportation generally or the trains specifically. Or you might find the use of the imposition of martial law in order to enforce correctthink, because of a distrust in individuals.
