The human population is finite, and exponential growth hits its bounds pretty quickly. In the long run, if you assume that most non vaccinated and a large part of the vaccinated will eventually get COVID (probably the case), then the 29% reduction in mortality does, actually result in a 29% reduction in mortality, and the exact same number of people will have been infected either way. The difference will be in timing; the people will have been infected more quickly, with the (severe) problems that entails.
