I don't think that will be the case, as there will be a gold rush once the possibility is proven and visible, everyone will try to get it, even the naysayers.
It will be more like the crash of prices from the Spanish mines in south America.
And then imagine if we'd used that as a reason not to produce it.
If you're worried about the rich getting things unfairly, focus on tax policy and closing all the thousands of loopholes. That's a lifetime's work.
Maybe; instead when this happens, e.g. hairloss and finasteride, I look at people desperately trying to fight aging and stay young forever and then replacing their worry about hairloss with worry about post-finasteride[1] depression and sexual side effects. Or the people who are obsessed with nootropics ('smart drugs') who are in a hyper-competitive world I don't want to be in at all. Or the people who slather vitamin A creams on their skin to try and look younger who may give themselves retinol burn[2] and Vitamin A, E supplements to look younger which may[3] gives bone pain, liver damage, birth defects, increased risk of fractures, skin irritation, increased risk of prostate cancer.

And I think your claim is wrong; a lot of people pop vitamin supplements like candy expecting that they are harmless and would be surprised to find they are capable of causing harm; anecdotally I have read of people saying exactly that, which is enough to disprove "wouldn't be surprising to anyone at all".
Because of the side effects, right?
> - yet people aren't rushing for healthy diets and exercise, are they?
Because that implies a lifestyle change. I think the assumption here is that this would be a treatment or a pill.

I don't think that most people will be surprised to hear that taking any pill can have negative effects, though I do think that lots of people may be surprised by the dose at which those effects are seen, but there will always be outliers, of course, who may think that eating an entire carton of gummy vitamins is no big deal. But, I don't think that is really relevant, although I'm not sure what point you're trying to make still.
I think you're trying to say that some people won't rush to take this pill because it may have unintended side effects?
I'm countering the claim "even naysayers will want this as soon as it works" with evidence that people don't want things which work - for multiple reasons, viz. known side effects, unknown/long term side effects, your 'implying a lifestyle change', not wanting to be early adopters, for examples we have covered, along with people who don't want to 'play God', don't approve of medical treatments, don't want 200 years of working life (as mentioned in the comments elsewhere on this thread).
That's not a "feeling", that are words you put into my mouth, to then call it a "feeling" of yours. And that's the top voted reply. Just lol.
