I think my argument would be more along the lines of creating a managed ecosystem, free of invasives but not necessarily free of introduced species. A "managed ecosystem" is what would be preferable in commercial farming or forestry operations rather than a monoculture after all.
I believe it is easier to propose a holistic solution than treat rewilding as separate from commercial operations too. I'm not sure if it's possible to be a purist when it comes to Irish fauna. See: the last paragraph of the abstract in this. www.sciencedirect.com/science/arti...
