> That's because they haven't came out with another small iPhone in more than four years.

They also haven't come out with another iPhone with a headphone jack, yet no one kept using those.

I get what you're saying, but what I think is that the average mini buyer is inherently someone (on average!) who changes their phone a lot less often. They're less likely to be glued to their phones. Bigger phones = more infinite scroll addiction, and so on. Apple doesn't want to cater to the mini buyers.
