Trump's travel ban didn't apply to US residents, was limited to people who had been to China but was after the disease had spread to multiple countries, including the US.
Spain was the main country where we imported it from. We had months between the initial outbreak and then to develop plans for managing it. I doubt that we could've kept it out indefinitely but we could've delayed it. We could've maintained a test and isolation policy for longer, if we had kept numbers down.
The argument playing off public health and economic impact is false. The countries that have suffered the least economic impact are the ones that were proactive and lockdown early.
The most important thing would've been maintaining track and trace though. A travel ban in isolation would've done nothing.
