The assumption is that the wires has an uniform voltage. My question is what principle assure that we can approximate that the wires have an uniform voltage ?
The resistance of the wires is negligible in comparison to the resistors and other circuit elements.

That's very nice. The puzzle is almost complete. But what assures that the current is constant throght all the circuit
Say in a segment (current flowing from left to right) at a time to its left current is high and to its right its less..........
So to conserve charge, some charge stays at the junction.............
Now due to this piled up charge electric field will now push the charges on its left opposing their flow and push those on its right to support their flow........
The higher current eventually falls down and the lower current Eventually rises up....

This happens till they are again equal

When there's any change, an EM wave flows. That's the way to look at it.
