The richest segment of our society is "old people" who have worked their entire lives and amassed personal assets. I agree that they will spend their money on anything that will alleviate their pain, improve their health, or give more time to indulge in the joys of their life (whatever they are). No law can prevent that, nor should it in a land that purports to guarantee us the "pursuit of happiness" and all that entails.
Well a law can prohibit funding to slow down the invention of the aging process interfering agents the rich geezers want to buy. A law can achieve that.
