I don't know why you're getting so much pushback... Planetary resources are finite. If you give up dying, you have to give up reproducing beyond the replacement rate. People like to imagine they'll be part of some small tribe of a lucky few immortals, but the reality is we'd be in exactly the same situation as today, but with a population rapidly screeching beyond all known sustainable limits far faster than it is today. To name just one obvious problem.

Success of something like this entails a way to regulate reproduction at a far more draconian level than even China's one-child policy. I don't think any civilized nation could impose a "no child" policy and remain intact.
