This serial is not about nuclear family where there is no interference from the elders or the elders are no more.
This is an in between serial where husband and wife coexist in a family respecting the elders while the elders look after the welfare of the entire family. So some individual decisions will be over riden. I feel this teaches people how to live in society, how to give and take and how to move along. Too much freedom leads to other problems like ego clashes between husband and wife. Too many restrictions make people depressed and oppressed. So a healthy balance can be struck.
