You are talking about personal reasons that people need more space, which is absolutely true. I am talking about a fundamental shift in how we perform work as a society. If everyone, all at once, starts working from home and avoiding offices, it is reasonable to assume that some of that office space will need to be re-created in houses, which will increase the necessary size for houses. Things like the average size of a new house and the average amenities people include (an extra office, an extra bathroom, a separated "play area", mesh wi-fi friendly, etc.).
