Potentially. In 62 it infected 4 million and hospitalized ~ 48k. Today that infection rate might be just as high, there is little to indicate that hospitalization rates would be lower. perhaps some medical advancement would have been developed to reduce the severity of the infection and lower hospitalization, but there is no guarantee of this. Of course instead of this they just developed a technology to trick your body into fighting the infection thereby creating immunity. You would have to prove the vaccine is worse than this alternative and I see no evidence that this is the case🤷‍♂️. In developing countries with low vaccinations rates the death rate is over 5% clearly there is no magic bullet medicine that solves for measles in places that lack sophisticated hospital systems.
