This is about as close to "eliminated" as you can get; the new cases are all from incoming international travel.
This directly refutes the OP's statement that lockdowns "won't stop the virus."
Early on when New York was surging and Trump suggested limiting inter-state travel Cuomo suggested that would be akin to a federal declaration of war. [1]
It can be true that strategies that might work for New Zealand could never possibly work for the continental US.
Hawaii has a similar situation, got new case count down to zero for a few days, but are dealing with a few cases per day recently.

Unlike many countries, they can easily close their borders, many people live in isolated communities and they aren't a major transport hub.
Unlike NZ, the US can’t control its borders - as decades of uncontrolled illegal immigration has shown us.
I wish we could be done with this absolutely false misinformation. Case in point, New Zealand is COVID free.
