Well with the plunging birth rates in developed countries, I think this would be feasible. Robots and automation would solve the economic issues of having an inverted pyramid entering the workforce. We would in a sense become long-lived rich eloi.
However in pockets of the world which won't use contraception - such as religious states, or poor areas, there will be age-old issue of producing a lot of babies who go and consume the resources of the "1st world". These places still exist on earth and the lives produced there are just as valuable so the ethical question would be, how would the rich countries deny the life extending medicine and procedures to others? It almost has to be a function of population growth.
I wanted to write a novel one day about the year 2278 when a couple of married Elders finally decides to have children and therefore forfeits their access to prolonging their life more than 50 years. The idea is that it would become one or the other.
I guess there could be religious arguments for not using the life extending medicine, since god didn't make humans with that longer life-span. So if there are arguments against contraception, they could also be used against long life.
