True but by denying access to new potential cases you can limit the spread. Controls do nothing if people come into the country or travel internally regularly that are sick
The problem isn't controls do nothing - but our internal controls are so lackadaisical that they are ineffective at stopping local spread, travel ban or not. What travel ban provides is buying time to vaccinate our population before the strains invariably arrives and spread (because it will, and no system is truly air-tight)
