Nah, this is horseshit. Your point is true if we're talking about matching to the absolute finest detail, then it's not (always) important. But that doesn't mean because having the finest level of accuracy doesn't always matter that we should just tolerate absolutely no reference point at all. It just casts way too wide of a net and makes the experience absolutely shite to audition captures. If we don't draw a line at all, then how many dB should we be reasonably expected to guess within? +/-1dB is negligible, +/-5dB starts becoming annoying, and +/-10dB is more like "fuck this shit".
There are also absolutely situations where you would want things aligned 1:1, for instance in a studio environment when doing overdubs, or when using a studio tone on tour. Ultimately everyone's requirements are definitely and just setting the bar really low is unbelievably (and unnecessarily) short sighted. If Line 6 or Fractal just randomised all their gain staging (per amp model) for no reason and told users "nah, you figure it out" people would rightly say it's insane.
