... people pretending to ignore the blinding obvious ...
This basis of this thread is an argument about what the definition of "good enough" is.
What you are missing is that the advantages, of any format or tool, aren't necessarily obvious, nor cheap, nor important, nor meaningful, to any other given person.
"Good enough" is a purely personal decision.
For example, since I know how flash works and know how much it can improve my work and I have good lights: I get pissed off at myself when I need to print negatives where I was too lazy to grab and carry a speed light. I like fill flash so much that it is regular to see my fancy Nikon SpeedLight on top of my Holga or tethered via an extension cord at any time of day, that combination creates an incredible tool for creating a fun look that's really easy to print. The negatives are big enough for me to sort easily, and I don't have to worry that the grain is going to compete with my subject matter.
This kit took real work to learn, it takes real faith in and understanding of the limits and strengths of the films I put in it, and to understand how to make the best of the lens. It took hundreds and hundreds of hours to sort and learn and refine all the skills needed to make the kit work well.
In use now though, for me it is a true joy, and I wonder why people sweat so much about exposure and development. Once the film is loaded/chosen, my biggest challenge is simply to remember to focus, beyond that it's P&S with nary a thought about the camera or exposure. I get to think about composition and how I want the light falling and other artsy fartsy stuff like getting my subject to giggle or cry.
I don't see a lot of other guys hauling a kit like this around. That shouldn't be a surprise.
