I think it does make sense to have some work places allow this, especially when there is no actual work to be done.
Having said that, it might also open up a door for abuse, depending on the character of the individual employee of course (i.e. partying the night before, then sleeping at work).
Still in another sense, I'd like the world to be organized in such a way where people are not forced to do anything that feels unnatural for them.
