I disagree. The number of deaths is fewer if those who get infected first are low risk groups. In Sweden, schools stayed open, so there will be fewer deaths.
That’s a good point. If in gaining herd immunity they mainly allow the stronger members of the herd to be infected (and gain immunity), then there will be fewer deaths along the way. And once they’ve gained herd immunity, those who remain uninfected will tend to be the most vulnerable, which is precisely what you want, and they will be shielded by the immunity of the others. So I agree Sweden might actually reduce the total number of deaths rather than just changing their distribution in time.
