Because unlike our world, the Star Trek world actually respects people’s privacy. Ever noticed how people just vanish from the ship and the computer never alerts anyone until someone asks for their location? When Trek was written, the idea of constantly monitoring and reporting on individuals was abhorrent. It’s disgusting how willingly people just accept that now.

But like, they can still track you. And removing the badge that lets them track you is basically a crime. Also section 31 exists basically just to track and monitor people.

They can locate you. They don’t actively monitor you. That’s a big difference.
