Israel experimented with communally raising children within the Kibbutz system, but as far as I know the results weren't super encouraging and few places still do it
Kibbutz's failed because there's no incentive to do any work, same with every other form of communism that's been tried. Reworking daycare to be a more holistic experience than it currently is is a very different idea.
With what legal authority? Even the Knesset back then couldn't pass more ambitious laws. Let alone in 2023 or in most other countries.
Communal childcare in kibbutzim is not related to economic success - I know people who grew up like that, they gave up on it because the results for the kids were seen as negative. Even in rich kibbutzim with plenty of resources they've phased out communal childcare and children live with their parents.
