Anyone who has ever heard a 128kbps mp3 side-by-side with a 320kbps (or really anything above 192kbps in my experience) version can tell you that bitrate definitely matters. The better audio equipment you play it through, the more noticeable it is.
It definitely becomes inaudible at a certain point, but back in my CD ripping days, I'd scoff at anything below 192kbps
Have you ever done an actual double blind listening test? You'd be surprised. Even with good listening equipment it can be very challenging.
Have a go on the 128 kbps AAC test on this page and see how you do:

I have, yes.
Presumably it was using an older/outdated codec then. With modern encoders, especially with codecs like Opus, Ogg, and Apple's AAC, the vast majority of listeners find 128kbps to be transparent, and certainly nowhere near night-and-day when compared to lossless.
