The only advantage I see is the use of 3 networks(for those who live in places with bad coverage).

You're calculating the prices based on hitting the data ceiling on Fi every month, if you are hitting the ceiling that often then you shouldn't be on Fi. T-Mobile's family offering is likely better value for true unlimited.
In general I agree Fi isn't great for families, because kids often consume a ton of data. It might be good for a spouses if both parties don't use much data.
Does Google Fi offer plans for groups or families?
Yes. If you’re new to Google Fi, you can set up a group plan during your checkout process. Just have the intended plan owner click “Join Fi” to get started.
Just like an individual plan, each month you’ll pay $20 for unlimited talk and text, then add $15 for each additional person. Data costs the same at $10 for each GB used.
If you’re already a part of Google Fi you can invite people to your plan here. You can have up to six people, including the group owner, in a group.
For 6 users, the max you will pay will be $275 (data is free after 18GB), minimum $95 (no data used).
For 4 users, the max you will pay will be $205 (data is free after 14GB), minimum $65 (no data used).
For 2 users, the max you will pay will be $135 (data is free after 10GB), minimum $35 (no data used).
