The thing is, none of these problems happen the instant we solve death (and "solving death" is not itself going to be instant). Life expectancy will increase, population will gradually increase with it, and we'll be able to see the problems we have to deal with as a result a very long way off. It's similar to an argument people sometimes give me when I tell them I'm vegan, which goes along the lines of "If everyone suddenly became vegan, imagine what that would do to the world economy! How would we feed all of these people when our food producing infrastructure is animal based?" And the reason I don't worry about that is that I know that scenario isn't going to happen. When people stop using animal products, which I think will happen - not for ethical reasons, but for economic reasons as cheaper, more authentic substitutes arise, and the sustainability of animal farming dwindles - it will not be an overnight process, and the world will have plenty of time to adjust. It's basically the same with extreme longevity. We don't have to solve these problems with the tools we have today, because we don't even know when they will be problems that need solving. And we have no idea what tools will be available to us once we actually do have to solve those problems. But if you flip the scenario around, and imagine that everyone already lives forever, and these problems start to show up, do you really think that anyone would even think to suggest "Let's have everyone die after around 70 years or so"? That idea would be grimly hilarious in a very Modest Proposal sort of way.
