Despite all this, human cases of rabies still happen. Fortunately it's rather hard to spread rabies between humans and it's symptomatic by the time it becomes infectious. In the case of an easily airborne virus even with such measures available like vaccination and prophylaxis for possible exposure, it seems daunting to the point of impossible even in a very wealthy country. In the developing world it would be certainly hopeless.

Genetic surveillance is just around the corner, and will soon be / is now within reach even of developing countries, with solutions like Oxford Nanopore's ultra-portable sequencers.
The virus is here to stay. Eradication is a total fantasy, just a distraction and waste of time.
Then you're left with the "leaky bucket" of transmission between humans and animals... But this is a known vulnerable point which could be monitored effectively and very cheaply.
