First I did not say we should keep ecosystems stable, I don't believe that.
There is a difference between non-native and invasive species.
Non-native species: These are species that have been moved from their native habitats to a new environment, usually as a result of human activities. Non-native species can be any type of organism, including plants, animals, fungi, and bacteria.
Invasive species: These are non-native species that not only survive in their new environments but also reproduce rapidly and spread widely, causing harm to the local ecosystem, economy, or human health. They can out-compete native species for resources, alter habitats, and disrupt ecosystem functions.
invasive species invade an ecosystem and mess up the ecological balance. Many species go extinct and a new ecological hierarchy is formed and the landscape changes. Isn't this what has been happening for eons? How did marsupials get to Australia from America, how did horses take over the Eurasian steppe, there are many example like that. Who are we to "manage and conserve" biodiversity? I don't think we have the power or the right to do that. just my 2¢.

Here is a study on Stinknet in the Sonoran Desert. If you read through it I think most would say is qualifies as invasive in this environment https://sdcwma.org/docs/stinknet_desert_plants.pdf
Conservation isn't about keeping the environment in a bubble but rather being stewards promoting the overall health of the ecosystem.
