Yes, that's my point. Capitalism is bad, not increased lifespan.
However, given a capitalistic or otherwise zero-sum/proprietarian social system, I cannot support inegalitarian life extension as moral. You need a broadly egalitarian society and broadly egalitarian life-extension.
As long as we have social systems designed to maximize strife and toil, we should be working to destroy those social systems and replace them with systems for creating peace and happiness, yes.
Medicine and life extension as a public service is great. As a private luxury of the rich it's abominable.
Think about the implied statement of making radical life-extension available to the rich alone! "Whereas I will live to 160, you will only live to 80. Because I can afford these treatments, it means my life has double the moral worth of your life."
If you honestly believe that moral worth and financial net worth are two different things, you cannot support setting lifespan in accordance with money. Period.
