All that you said is perfectly valid for your usecase. But you can't just make your use case a generality.

Some people have a camera because they want to take better pictures than their smartphone but don't want to bother with post-processing, some have tried manual processing and found that the work/result balance was not doing it for them, some think that JPEGs look perfectly fine, some just don't have the time to do the processing... there are myriads of reason for which people would like to land somewhere between “let iOS do it” and “I systematically chose my ISO according to this Darktable script I developed these last years”.
