This is a quite crazy objection that puts imaginary points (money) before the well-being of people. Just what are we going to do with the money, once we’re sick and one step away from the grave?
The first thing you need to realise is that, when you wonder ‘How much will it cost?’, you’re actually wondering how many resources and how many people doing how much work it will take to do something. That’s all that really matters. The problem is that we have a sucky economic system where even if we do have more than enough people and resources to do the job, the monetary cost of it could be so high that you can’t get the job done without creating financial problems left and right. This should be a hint that the problem, if it exists, lies in our crappy economic system, not in rejuvenation itself or whatever other thing we may create.
Apart from the obvious fact that other hysterically expensive endeavours (such as space missions) are pulled off despite their costs, we must take into account that desperate circumstances call for desperate measures. We don’t need to tear apart our economic system and replace it with another before we create rejuvenation, and neither would we if faced with another health crisis (such as a pandemic) or a planetary crisis, but we need to get the job done despite its costs and the consequences they may have. We can’t reject rejuvenation on the grounds that it may be too expensive, just like we wouldn’t in the case of an existential risk. Can you imagine that? There’s a huge asteroid on a collision course with Earth, and our only hope relies in a spectacularly expensive space mission to destroy it before it’s too late. Just who in their right mind would step up and say: ‘Nah, too expensive. Let’s not do it.’ What would we do with the money we saved, keep it for a rainy day? I’m not sure it would help much—in the circumstances, it would probably rain fire for a while.
Like it or not, ageing is an emergency just as much as a potential asteroid impact or a lethal pandemic. Everybody has ageing, and everybody will develop debilitating age-related diseases that will eventually lead to death. The problem of an ageing population is quite real and going to get worse with time. Cost what it will, rejuvenation needs to be done.
