In order to stop seeing "millions of new cases", every source of new cases should be reduced.
International travel is an orderly place to apply a filter, just as hospitals test all admits (even those without symptoms).
Blocking all visitors from specific places – even places with lower rates of prevalence than here! – was silly theater. This is actually well-targeted to reducing the interactions of the likely-infected with the uninfected.
(If a city or state/province even wanted to set up internal borders, & require on-the-spot quick antigen tests to enter regions of actual or attempted-infection control, perhaps even anonymously, that'd also be a well-targeted intervention far better than the other theater we've been fed so far.)
