If remote work proponents want remote work to become a thing, downvoting the parent into oblivion doesn't make their case to the managers and Marissa Mayers out there who are against it. Address the concerns that some people are far more productive on-site. Pretending it's a non-issue doesn't help and it is often not an easy thing to police.

It's not as simple as "don't hire/work with those people" either, because we don't always have full control over that.
