For a law to be legitimate in the USA, it has to derive from the powers ceded to The Government via the US Constitution. Any law that limits my rights as a US Citizen under the US Constitution is invalid no matter how good the intent.
Your willingness to surrender your fundamental rights - such as the warrrantless telephony puts you in the very category of indviduals that folks like Benjamin Franklin and Patrick Henry warned us about:
Those who would sacrifice any of our precious liberties for a temporary measure of security, deserve neither liberty nor security - Benjamin Franklin
Give me liberty or give me death - Patrick Henry.
And your assertion
The only person I know who has a reason to object is the person who has something to hide, real or perceived.
Is patently false. We have already seen many individuals, US Citizens included that have been sent to Gitmo or worse despite being innocent. So when you surrender your liberties to the government so that "your family can fly more safely", you are empowering just that.
And you have no guarantee that your family can fly more safely. In point of fact there is very little in place today to prevent another 9/11. I travelled some 50,000 air miles in the 3 mos after 9/11 and an additiona 150k since that time and the "security" you see at airports is a PR job designed to make you FEEL more secure.
So trading your liberties for a false or temporary security puts you on the same side as the people who arrested my grandfather, "harshly interrogated" him, sentenced him before a tribunal as a "danger to national securty" to indefinate detention and then allowed him to die from the injuries sustained from that torture.
Note that by speeding, you are contributing to a new 9/11 every month or so (speed is the primary cause of fatal car accidents). Someone illegally entering the USA and committing no other crime actually IMPROVES the USA.
So frankly it seems to me that you are the problem, not them
