Traveller was originally written pre-the surveillance society, when computers weighed 4 tons and barely had the bandwidth to run a digital clock.
Yes, the temptation to make the 3I a total surveillance society is so seductive to those in charge that you'd think everybody would be snapping up the tech the second we reach TL 7.
There's a problem with that. So many people can abuse that system that it won't work on a grand scale. It's about rights, including the right to roam which is the core of Traveller - your characters want the right to go where nobody knows your name.
Then you have the aliens - Hivers, Aslan, Vargr, Zhodani - who might take exception to having their rights curtailed in the 3I. People have launched warfleets over far less.
Besides, the Zhodani would never need tech to maintain a surveillance society. Everybody is conditioned to be too darned honest about everything that it would never occur to them to set up systems predicated on the idea that people as a whole are not to be trusted.
Surveillance societies are, at their core, afraid. They fear change. They fear time. They fear things they don't understand, which are above their EDU. They are afraid of everything, because they don't know how things work, and as an act of fear they set up Big Brother to keep people under their thumb.
Your Travellers would be the first to tell Big Brother 去你的!
