"We are family" is only meaningful if everyone has a meaningful share of equity, and that does not scale very well. An actual family shares resources. I personally know that I will inherit some property from my parents. My parents took care of me when I was young, I have helped them in recent years. That is family. Among commercial relationships, the only thing that comes close is a partnership where everyone has some significant amount of equity. And that doesn't scale. A partnership of ten people is often like an actual family, in the economic aspects, and maybe you could stretch that to a hundred people. But you could you stretch that to 1,000 people? Or 10,000 people? At some point it is just not possible.

Also, many workers enjoy working from home, but in terms of approaching the feeling of true alliance that is implied by "We are family" the only places (that I've been at) that have come close have been small startups where everyone had equity and everyone was working in one office.

Mind you, when I say equity, I mean actual equity, not stock options. And to get actual equity, typically a worker needs to bring something to the table, other than a willingness to commit future hours. Typically they need to invest their own money, and become a true partner, or invest something else of value (one of my partners had inherited an old farmhouse and donated that, which became our office).
