I can imagine situations where it would be objectively oppressive, or at any rate limiting to personal development. If you're supposed to marry but don't want to, for example, or if you have a disability and only the family to help your progress. Needless to say, families can have limited knowledge or limited opportunities for you to find a role. They can be anxious and restrictive, however much they love you. A social system which focuses some care or opportunities outside the family can be better informed and more productive - with better chances for education, work and social life.
And for older people with only adult children to help them, I can imagine people who would rather be in a well-run care home or supportive non-family community where there are more things to do and friends to make. Of course this kind of thing runs the risk of promoting institutions which aren't adequate to people's needs and self development but as a general principle I don't believe a system weighted towards a lot of family involvement or responsibility is necessarily a good system. And, alas, the struggling figure of the child carer or the young adult, often female, deprived of personal opportunities because they need to look after an older adult isn't limited to our immediate society.
But, as you say below Rick, having no family or community doesn't work well either. And societal institutions without family involvement can lead, as we know, to awful abuse.
