Even across a single country there will be variation in the effectiveness of local measures. When you have this dispersion in R0 what happens is most places go to 0 like you hoped, but some places don’t.
Since that dispersion is unavoidable, you need a fractal system of borders—strong borders around countries, medium borders around states and cities, and weaker social distancing measures locally. Then the problem areas don’t spread much, and they can be defeated in detail.

Look at the map of South korea after the superspreading event: https://imgur.com/l7RD345
98 cases in Seoul (pop: 10 million) and frickin’ 4000 in Daegu (pop 2 million).
