Should we build a real-time database with all citizens and their probable infection status, and synchronize it with phone locations to trace all physical encounters?

I doubt it is technically feasibe. Even if possible, the geolocation imprecision in a metropolis would lead to blooming contact chains that are too large to be useful if movement is not very severely restricted.

Every smartphone has GPS now, we could trace the entire path of everyone throughout the day if we want, and make it mandatory to keep location tracking enabled

In the subway, parking garages and multilevel department stores?

It probably does not need to be perfect. It needs to get R0 below 1. Highly frequented public places can get indoor GPS beacons.

Technically possible? Sure. Within a few days for Europe? Nope. Also: This starts to sound a lot like a technical solution for what is, at its core, a social problem.

Most social problems don't have social solutions, or crime would not exist. You need to change the actual constraints and incentives.
