It's the opposite actually. WFH is more efficient, but efficiency is not the reason why we work.
Every self respecting man needs friends and enemies. The more watered down a man's life is, the less intense the friendships and rivalries are going to be.
WFH is just the last step in a long process watering everything down, where the commoditification of every experience is making us dull and full of apathy.
The problem is that a disease like that becomes endemic in society, so people's beliefs become weaker and weaker, but not having strong beliefs closely correlates with people having next to no belief in themselves, which again closely correlates with WFH preference because people think they don't have what it takes to thrive in an office environment because they are scared of the strong sentiments of friendship, rivarly, love and revenge on the workplace and in life in general.
