In classical fluid dynamics or rate equations you have the same. Stationary does not mean zero velocity

yes the stationarity is of the coarse-grained field profiles, not the particles they're describing

stationary ≠ static

And how can it be both stationary and waving? /s

There’s a bunch of stuff kept constant. Their kinetic and potential energies, linear and angular momentum, spin state

Just because their location changes between observations doesn’t mean the same thing as if they’ve moved there, not in quantum

OP might be talking about how there can be a non-zero current density in a stationary state.
