You can compress it for listening later, but you can never add information _back into_ the file. Store it in FLAC for archival purposes.
An equivalent would be archiving works of visual art in JPEG and not something lossless.

Only for some people -- the upper limit of human hearing varies between 15-20kHz, depending on the person and their age. For many children and younger adults (myself included), CRT coil whine is well within our audible range, as an incredibly annoying high-pitched squeal.
This comes up in speedrunning communities sometimes -- many runners prefer to play on CRTs due to their fast response time, and streamers who use CRTs need to remember to set up a notch filter on their microphone, or else their stream may be borderline unwatchable for younger viewers and the streamer might not even realize it.
Why not then? Because there is a ton of science and empirical evidence that humans cannot hear the difference[1]. Good engineering is about meeting the requirements with minimal cost. If the requirement is that it sounds good to humans, and the cost is number of bits to encode (and thus store and transmit) the signal, then modern codecs like Opus are clearly superior to uncompressed and losslessly compressed signals, much less higher sampling rates.
If your goal is something other than good engineering, for example the aesthetic satisfaction that the bits are the same as what the mastering engineer put on the CD, or for some reason caring how clean spectrum plots of artificial signals look, then the arguments may have some merit. But let's be clear on the goals.
