There are certainly individuals who refuse to learn how to do whiteboard problems on principle, and if they are having trouble finding a job, I'm fine with that. They'll probably be a pain in the ass to work with.
However, my concern with whiteboard problems is that there are plenty of people who are really good, but get terrified in a whiteboard situation. And some of the absolute smartest people aren't able to think quickly. That is to say, for most questions, everyone else will get the answer first, but for the hardest questions, nobody else will get the answer at all.
