At first glance this sounds reasonable. But when you actually examine what a demographic collapse on a grand scale could look like - it's possible that this amount to the kind of suffering that we haven't seen in a century. There's no way to know, because it's uncharted territory, but the potential downside seems huge. "maybe lower the population a little" - some societies will have some gradual reduction in population. Many countries are already or will soon have their populations of young people decline drastically. Our societies are pretty fragile systems, and when you change the ratio of young to old at the rate we're going to, it's hard to anticipate how these systems will cope.
