You bring up the parallel with invasive species—I want to expand on that a bit. The enemy release hypothesis holds that species become invasive not because of any properties inherent to themselves, but because in their new environment they are no longer contained by the other species that co-evolved to regulate them in their original ecosystem. In the case of colonial-era Europeans, this meant the commercial institutions that had evolved in the context of the moral authority of the church and the regulatory power of local legal systems were freed of those constraints when they left Europe’s institutional ecosystem.

In principle, this could have gone both ways (and possibly did, in the case of the ideas that sparked the Enlightenment), but by controlling the shipping, colonialists acted as a sort of cultural version of Maxwell's demon—allowing the spread of invasive institutions in one direction but not the other.
