It's so tiring engaging with the public about this. No.
Literally the only indicator you need to look at is R_t, and R_t was less than 1.0 at various times in various places throughout all of 2020. All you need to do to make an infectious disease go away is keep R_t below 1.0 for long enough (this depends on the lifecycle of the pathogen, but in this case we're talking weeks).
You need to keep it low enough, for long enough, with no reservoir. It's the last part that's the problem. You'd either need to prevent all travel for years, or arrange for everywhere in the world to take action at the same time. The latter is basically impossible.
I'm sorry, but no. Yes, this might work at an academic level, but dealing with the politics of the world and human nature, this thing that you ask cannot happen given the diversity of the politics and cultures of the world.
It's the same reason a carbon tax type system will never work, because there will be some subset of our world that would want to take advantage of a situation for their own financial gain, even if it hurts everyone else in the long run.
But it simply didn't happen. At all in fact, once you look at the whole world. And all of this is based on reported data. We never got a clear picture of what unknown transmission looked like. If I had to guess, it was many-fold worse.
