Well, this is certainly a disputable issue, but it is not from failing to read the Bible.

It is true that 90% of self-identifying Christians are guilty as charged - they know little Biblical Truth to the point of not even qualifying as Christians. Jesus' ultimate response to them will be "Depart from me, I never knew you."

But for those who take their Bible's seriously, here are a few of the reasons they tend to obey the governing authorities (except when they can find a suitable loophole):

Paul's words from his letter to the Romans 13:1-7:

Let everyone be subject to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God. Consequently, whoever rebels against the authority is rebelling against what God has instituted, and those who do so will bring judgment on themselves. For rulers hold no terror for those who do right, but for those who do wrong. Do you want to be free from fear of the one in authority? Then do what is right and you will be commended. For the one in authority is God's servant for your good. But if you do wrong, be afraid, for rulers do not bear the sword for no reason. They are God's servants, agents of wrath to bring punishment on the wrongdoer. Therefore, it is necessary to submit to the authorities, not only because of possible punishment but also as a matter of conscience. This is also why you pay taxes, for the authorities are God's servants, who give their full time to governing. Give to everyone what you owe them: If you owe taxes, pay taxes; if revenue, then revenue; if respect, then respect; if honor, then honor.

Peter said essentially the same thing (1 Peter 2:12):

Live such good lives among the pagans that, though they accuse you of doing wrong, they may see your good deeds and glorify God on the day he visits us. Submit yourselves for the Lord's sake to every human authority: whether to the emperor, as the supreme authority, or to governors, who are sent by him to punish those who do wrong and to commend those who do right. For it is God's will that by doing good you should silence the ignorant talk of foolish people. Live as free people, but do not use your freedom as a cover-up for evil; live as God's slaves. Show proper respect to everyone, love the family of believers, fear God, honor the emperor. Slaves, in reverent fear of God submit yourselves to your masters, not only to those who are good and considerate, but also to those who are harsh. For it is commendable if someone bears up under the pain of unjust suffering because they are conscious of God. But how is it to your credit if you receive a beating for doing wrong and endure it? But if you suffer for doing good and you endure it, this is commendable before God. To this you were called, because Christ suffered for you, leaving you an example, that you should follow in his steps.

Ponder that.
