It all depends on need. The idea that everything needs to work the same way is unsound. Arguably, the company I work for doesn't need to bring everyone into the office every day; we seem to be doing quite well. Another firm that believes it sees better creativity when people are in the same physical room may be better off not having their workers be remote. And like you say, not every company necessarily gets a benefit from having an 8 hour day. Depending on the nature of the job, the remaining hours of the day can be a diminished return, in which case one might as well give up on the game of charades and just allow their employees to go home.
