Short version: I am really twitchy around people who idealise an unattainable state of independence (particularly people who are doing so by ignoring or minimising all of the ways in which they do depend on people); interdependence is a Big Fucking Deal, you're less likely to fuck it up if you're aware of it and taking it into account, and I am fundamentally not capable of a lot of the things that frequently get swept up under the heading of "solo poly".

This doesn't necessarily mean it's a Wrong Thing To Do, obviously: but I think it is a problem to set it up as The One True Way (because it's always a problem to assert TOTWs, but also because it's a fundamentally inaccessible vision), and it's not a mode of setting up one's life I can interact with with any degree of intimacy, as best I can tell from my understanding of the approach.
