For example, you quote non-nativeness as a self-evident negative property of the plant. But this is highly debatable. It is not clear at all what nativeness means in the plant world (really) or if it really is undesirable. There are some common ideas around being 'not beneficial to biodiversity' for example, but it turns out plants are relatively quick to adapt and gain relationships.
Dismissing these perspectives as non-sequitur and not worth exploring isn't really contributing to an insightful discussion. I'm not saying weeds are good or something like that, I just want to convince you this actually is worth noting and exploring.
