if everyone in an area gets rid of all their invasive plants, then it'll be vastly easier to keep them from coming back.
I think this is a denial of what "invasive species" are, and even evolution itself.
An invasive species is something that thrives in many environments and outcompetes natives.
Since humans have become concerned about such things, loopholes in human thinking, behavior and social institutions are necessarily part of the fitness function that makes something invasive.
People can target something specific on a micro level, but at a high level, "invasive" will itself evolve to whatever works because people are psychologically or institutionally blind to it.

Have you ever tried to mow thistles or vetch?
