You implied printing is tech illiterate. I've had to print web content for many reasons, including sharing it with strangers whose email/phone/messenger I don't have. Or a group of people whose details I do have, but I don't necessarily want to fill their inbox with this content.

You also can't highlight interesting parts or scribble notes on a web bookmark. You can print it to a PDF or paste in Word and annotate that. But aside from it being much clumsier and messier as an approach... it still needs decent print styles to print to a PDF.
