EDIT: Had forgotten for a second that we can know ask this kind of questions to a computer, "straw man argument".
Yeah, who needs "X". I won't even bother with the "the rich" stuff, because, frankly, it's too tired, pathetic, childish and naive.
Crazy, I know.
How would I be able to enforce it? By somehow keeping the costs high? By lobbying?
Nothing would work, because this would be too big for the working class to just sit there and watch, and if lots of people get really pissed, it can turn very ugly, as history has taught.
People will want it and they'll get it, one way or the other.
So you might have doddering 120 year old ancients (potential predicted life extension) with ever more brain damage.
Sadder day for those who only sees tragedy in progress.
We could be in a similar situation with anti-aging drugs. Plus, with citizen science projects making ad-hoc labs more accessible than ever, there's a good chance that normal people could make their own versions of these anti-aging drugs, assuming that science journals and informatic pipelines remain accessible (the current rent-seeking of top journals lends some small but worrying evidence against this).
