if i physically cannot type the punctuation, its presence in my work would have to be the result of something other than me putting it there.
now, i can't speak for anyone else's usage cases, but if there are emdashes then they're either using a fancy ass word processor that inserts them or they're using AI and that "or" is too suspect for me to overlook.
Word autocorrects 2 hypens in a row to an em dash, and even in google docs you can set it to autocorrect nearly anything you want into an em dash. There are valid uses for it that normal humans do use. Maybe not in casual conversation, but in journalism, legal work, books, etc. there are reasons someone might choose to use one over structuring their writing another way
I have autohotkey set up so that alt and alt+shift hyphen produce en- and em-dash in whatever app I'm typing into, with no fancy ass required. The fact you can't physically work out how to do that is your problem.
