Linkedin isn't optimized as a physical resume.

If all of the important information doesn't fit on one page, in a way that is nicely organized and looks good, then it is not a resume.

Nobody should ever print out their linkedin profile and then hand it to a recruiter.

LinkedIn has a PDF export and I see plenty of exported LinkedIn profiles when doing candidate interviews.

Seems to work for a lot of people.

Sure, and the PDF export produces a shitty resume.

Yes, you CAN do it, and some people indeed do, but my opinion is that this is a poor idea because the service isn't optimized for it.
