On the other hand, a part of becoming an expert in some field should be getting to be _realistic_. Learn not to deceive yourself.
I can give you an example from my experience. I got annoyed by my dull knives, so at first I went and bought really expensive knives, the ones made of hardened high-carbon steel that start rusting if you look at them dirtily. And I spent hours reading reviews before buying them. That's probably the "most expensive cup of coffee" stage.
Then I stumbled upon a Youtube channel that explained how to sharpen knives properly. So I bought $70 worth of diamond sharpening stones and re-sharpened my old IKEA knives. And they started working almost as well as my set of ultra-expensive knives, but they are far more practical. The expensive knife set is now a display piece in my kitchen.
Another revelation for me was that past a certain point, there's really not that much difference in the quality of sushi. It's just rice and sliced fish. Sure, there are individual variations between chefs in rice-to-fish ratio, maybe some special soy sauce here and there, but these are all just matters of personal taste. So I now just enjoy sushi for its taste. And instead of a looking for reservations in expensive restaurants, I just drop by my local sushi place and just ask the chef to add a bit more wasabi to the rice.
I've watched like 3 hours of his videos on sharpening because he's pragmatic, approachable, and scientific, and now I actually understand how to sharpen a knife and why it works.
That's not a bad rule of thumb, but it's also easier to get dry, poorly seasoned rice, mushy fish, overdone or poorly done sauce and toppings combinations, and >1 day old uni than I'd really like at a lot of places.
Your advice makes sense when your local options are good enough, but I don't think you're actually arguing that quality doesn't matter -- only that beyond a certain point the additional discernment isn't valuable.
I went down the knife-sharpening rabbit hole a bit, too, but I only managed to make my knives duller with whetstones, even though I have good dexterity.
Eventually, I just took my knives to a professional sharpener and got the paper-thin, tomato-slicing sharpness I wanted.
Funnily enough, I had both an expensive "forged" knife and a cheap IKEA one, and the IKEA knife was sharper and held its edge much better.
