Lesterd, hit the nail on the head. If the government stepped in they would just demonise the governments stance and "obey god as ruler rather than men".

Display Christian Loyalty When a Relative Is Disfellowshipped
1 The bond between family members can be very strong. This brings a test upon a Christian when a marriage mate, a child, a parent, or another close relative is disfellowshipped or has disassociated himself from the congregation. (Matt. 10:37) How should loyal Christians treat such a relative? Does it make a difference if the person lives in your household? First, let us review what the Bible says on this subject, the principles of which apply equally to those who are disfellowshipped and to those who disassociate themselves.
2 How to Treat Expelled Ones: God's Word commands Christians not to keep company or fellowship with a person who has been expelled from the congregation: "Quit mixing in company with anyone called a brother that is a fornicator or a greedy person or an idolater or a reviler or a drunkard or an extortioner, not even eating with such a man. . . . Remove the wicked man from among yourselves." (1 Cor. 5:11, 13) Jesus' words recorded at Matthew 18:17 also bear on the matter: "Let [the expelled one] be to you just as a man of the nations and as a tax collector." Jesus' hearers well knew that the Jews of that day had no fraternization with Gentiles and that they shunned tax collectors as outcasts. Jesus was thus instructing his followers not to associate with expelled ones.--See The Watchtower of September 15, 1981, pages 18-20.
3 This means that loyal Christians do not have spiritual fellowship with anyone who has been expelled from the congregation. But more is involved. God's Word states that we should 'not even eat with such a man.' (1 Cor. 5:11) Hence, we also avoid social fellowship with an expelled person. This would rule out joining him in a picnic, party, ball game, or trip to the mall or theater or sitting down to a meal with him either in the home or at a restaurant.
4 What about speaking with a disfellowshipped person? While the Bible does not cover every possible situation, 2 John 10 helps us to get Jehovah's view of matters: "If anyone comes to you and does not bring this teaching, never receive him into your homes or say a greeting to him." Commenting on this, The Watchtower of September 15, 1981, page 25, says: "A simple 'Hello' to someone can be the first step that develops into a conversation and maybe even a friendship. Would we want to take that first step with a disfellowshiped person?"
