Maybe it is.
Maybe purist is the wrong word: obsessive better describes the kind of fascination that results in a practitioner spending more time fiddling with the gear than drinking what comes out of it. And that certainly doesn't describe the espresso-drinkers you meet in Italian bars - most of whom probably make coffee at home with a Bialetti.
I've done the bit buying grinder after grinder, swapping up for better ones, ditto espresso machines, compulsive temperature surfing, bottomless PFs, etc. I even had my own roaster Then came the epiphany that I was sinking a stack of good money into drinking two coffees a day - tiny coffees that were gone in under a minute, at that. Oh, there's a sort of Zen to it, certainly, especially with a manual lever machine that doesn't have any temperature control, but do you want the Zen or the coffee? Maybe you're getting both every time, and if that's the case good luck to you.
One thing you get out of a B2C is consistency. Another is speed and another is cleanliness. The coffee will never be startlingly good but given decent beans it's always good. In other words, it's a compromise, and IME it's a good one.
