Yeah. It's a strawman argument (especially equating non-native with invasive). I'd much rather have "schizos" dogmatically enforcing the native flora/fauna rule than someone creating an ecological dead zone by planting invasive bamboo in their backyard.
If we can recognize monoculture is bad, we can also recognize why invasive species are bad. To your point about cascading effects and to be topical - this is the exact problem with honeybees: https://www.sciencedirect.com/science/article/pii/S266651582...
It's all fun and games until the honeybees get sick, the native bee population is catastrophically depleted (due in part to the honeybees), and there is no one left to pollinate.
