rest of the world is ctrl-c, ctrl-x and ctrl-v. but emacs is in completely different world.
for emacs to gain mindshare, it needs to meet people where they are, not where emacs was 30 yrs ago.
of course, emacs does not work reliably in windows, so that is another issue
M-x cua-mode enables a variety of “traditional” keybinds such as C-x / C-c / C-v for cut / copy / paste

No, it's the same issue. In a Linux shell (say, bash or fish) ctrl-c is not "copy" but "terminate program". Most emacs editing keys (copy-paste, motion) work in the shell as they do in emacs, at least in fish and bash (and probably other places in Linux).
Learning that those shortcuts are arbitrary, application-defined conventions is the first step toward enlightenment.
