> The whole company town aspect of Apple/Facebook/Google/Oracle/etc. campus' seems so bizarre to me however. I just can't understand the benefit given the toll on the lives of the workers.

I wonder whether it's mostly risk aversion rather than an intentional "feature". The execs of FAANG _know_ that if they spend more money and put more people to work on adding features, acquiring users and expanding to under developed markets, they'll more-or-less reliably rake in billions for themselves and the company.

Most companies are experiencing double digit growth, so the upsides of decentralizing the offices is limited (even if say you reduce 50% of staffing costs, it's still not that great of a deal compared with potential lost growth and lost profits), and since nobody else has done it on a large scale before, the risks are (perceived to be) high and nobody wants to risk killing the goose that lays golden eggs.
