How you could stop the greed of someone wanting to sell those treatments to the mass market? I imagine Mark Cubin (or any other "shark" billionaire) would fucking love to be the first trillionaire or quadrillionaire by being the person who made accessible the treatments for aging. Cancer alone: the ego-boost and vast wealth for the person whose company/research helped "cure cancer" (hell, even just 1 type of cancer). these "sharks" would "chomp" at the opportunity I imagine.

If you are a member of an inner circle of an immortal oligarchy that already controls the most important markets, selling such treatments would effectively erode your already enormous advantage and fuel the would be competitors.

There is a lot of fake science out there and that could be used to reduce the market success.
