Earlier quoted context omitted.
"If police as a concept didn't exist already, no one would create it." Is there any evidence of that? Seems there are quite a few who support them as-is and many more who want to see minor reforms. What do you mean by quality of life problems? How do we plan to staff in that model given police response time already averages 5 minutes (would it then be 15, or would we have 3x the cost to fill 3x the positions)?

Sure, that's the not the same thing. Many people reflexively back the police because they perceive themselves as benefitting from the status quo or otherwise have it as part of their socio-political identity. Some people back the police because the…
Studies, surveys, anything at all to back up your claim. Sounds like there isn't (use of absolutes in your statement was probably the problem).
"Non-life threatening situations that have absolutely no need for someone with a gun to respond."
Depends on one's perspective and a bunch of other factors. You might be surprised about how many people carry guns in various professions (medical workers, mental health worker, various first responders, the general public, etc). The vast majority of people never have to fire their weapon. Most never even have to use their weapon. It's utility isn't solely based on being fired.
"In the hypothetical situation where we have all of these problems, but we don't have the police and never had, do you honestly think we'd assign all of these duties to one position?"
Yes, mostly due to staffing issues like response time and cost, which is something you didn't really addresses in your answer. You also mention things like domestic violence, which is actually one of the most high risk calls you can get.
You talk about armed personnel being more expensive. That's not exactly true. People become expensive based on the level of training they need/have. A gun is a part of that, but so are many other things like mental health training. You could still use police as responders for mental health issues with some level of training while waiting for existing social workers or medical professionals to arrive. Even under the model of using another type of person police likely have to show up in case things turn violent anyways.
"The police are unqualified to handle most of the calls they are called out to."
How so? Or is this another case of using the wrong words (most or unqualified)? If it's a matter of training, it may be cheaper to provide police with additional training rather than hire additional forces an incur all that overhead of benefits etc. The three things you mentioned were quality of life, violent situations, and mental health issues. You seem to accept that violent situations require police response, so would be qualified for that. Although there are numerous situations in the other two categories that could quickly turn violent an would likely require police presence even if they are not the sole responders. It sounds like the quality of life stuff are generally easy tasks that police are qualified to handle (you even mention a police report for a stolen bike). The mental health situations depend on the level of training. Relatively few departments have adequate mental health training. I think this could be handled with training on how to approach those situations and talk people down while the social worker or mental health professional arrives.
