Unless the guys on tech circles the TFA is mentioning are all singles and plan to stay so voluntarily or not, a (good?) portion of them have, had, or will have 3 year olds!

In fact I maintain one of those setups mentioned by TFA with some neighbours (lots of tech people/artists with rare media in the neighborhood for reasons), and friends and family in other countries.

The whole point of most of these setups (for people with family), is to be safe, simple, efficient, and low-maintenance for the whole family to be able to enjoy media.
