The Nyquist limit?
You need sampling at twice the frequency as a minimum to extract a time domain signal into the frequency domain. It says nothing about "perfect" especially when you're listening in the time domain.
There is a lot of data in the time domain that impacts sound/signal quality. As others have said though, it probably doesn't matter without high quality equipment and a good ear.
It's also good to note that you can train your hearing. A musician or producer or audiophile are going to hear things and qualities you don't. It's edge cases though, and generally irrelevant to regular listening.
You definitely can hear the difference between MP3 320 and lower mp3 bitrates though.
It is my admittedly limited understanding that we really can't do better at digitally recording an audio signal than how red book audio does it, such that the microphones, amplifiers, ADCs etc on the recording end and the DAC, amp and speakers on the playback end are going to be much more significant factors in audio quality.
Yes it does. You can use a higher frequency, but that does not change anything except increase the maxiumum frequency possible. Even with perfect ears and the best equipment, there is no audible (and mathematical) difference to be had.
Everyone who claims otherwise should watch Monty's explainer videos. I know they are quite old at this point, but everything he explains is still perfectly valid. If that does not convince you, nothing will.
