Let me preface by saying, I have my SUV all set up with a bed and a kitchen and all the amenities I need to camp out in the woods. I like it that way I’m enjoying myself I see no reason to change.
A couple of times I have mentioned that when seeing a doctor and the next thing I know, here comes the social worker with a stack of papers. I tell them that I’m doing fine. That I like how I’m living. I didn’t ask for any unsolicited help. And they don’t seem to listen at all. At some point they just leave me with a bunch of paperwork in a huff. I don’t understand why they get so upset just because I don’t want their help.
When I find myself becoming irked by someone offering help I don’t need, it helps me to think of things in terms of people who slip through the gaps: the system that the social worker is a part of strives to help those who need it, and you not needing that help makes you a false positive. You were likely flagged because sometimes when someone is living in their vehicle, this is a symptom (and reinforcing factor) of their life being in disarray. That is to say that some people who superficially look a lot like you are in need of support, and not catching these people would be false negatives. Bonus complication is that many people who do need this help may also be resistant to support (for a variety of reasons).
Given that no system is perfect, and the error rate will always be greater than zero, we can ask the hypothetical “is it better to have fewer false positives and more false negatives, or more false positives and fewer false negatives?”. Put a different way, when you’re bothered, that’s you slipping through the gaps in a system that has opted for more false positives with the goal of helping as many people who need it as possible.
Unrelated to everything else I said, I’m glad you’ve been able to find a way of living that you’re happy in — it is a challenge when the life that is best suited for us is one that society considers “abnormal”, so I’m happy to hear about anyone who has broken into what works.
