Might be because only 15% of the US Population have been vaccinated. That leaves 85% (I'm a math wizard) of us are vulnerable and can spread the virus. Trying to protect that 85% until they are fully protected requires masks, social distancing, hand washing etc. Until that happens travel restrictions, masks on airplanes and trains and in unknown groups need to be continued. Your question is apples and oranges.
