Govt intervene in Family Matters?

The example here can be used for:
1. How far should the state be involved in family matters?(DHS Mid-Yr 2012)
2. Discuss the appeal and the dangers of alternative methods of healing. (CJC Prelim 2005)
Other than health matters, consider these other areas where govt may/may not intervene: Parents' Maintenance Act, 'Eat With Your Family Day' Campaign, divorce, having babies, getting married, spousal abuse, child abuse, education(made compulsory by law in Singapore)......
