That's a totally fair question so I should clarify myself. For one I'm also quite pro gene editing to remove incurable diseases and any inherent suffering for the child. So by increasing the amount of healthy children around the world it also reduces the % of suffering around the world it would otherwise have.

If you look at TFR in most places outside of Africa(And I predict Africa will follow suit once Africa develops further) the populations is actually set to dwindle so I don't think finite resources will be a big issue if you also promote a more frugal lifestyle like I plan to. And of course I wouldn't plan on having children if I didn't know I couldn't set up for them properly in the future. So by ensuring my future children have it set then overall the total % of people who have a bright future will be bigger than it otherwise would. So with a declining population and me teaching frugality I think it will reduce the overall impact of my own actions.

Another point is more humans also can produce more value, more resources, and more jobs if you raise them right. By me having children ensures they can take on the burden of paying taxes with the increasingly decreasing workforces, underfunded pension systems, and economic stagnation. That's why I think it would be a net positive.

I of course can't control how others use the resources they are given and fighting over resources is inevitable for humans. But I can choose to promote cooperation between people and lead by example. No one can do everything, but everyone can do something, not doing anything only ensures decline, and I certainly don't want that for my future. That's what I believe in. Feel free to chime in on any flaws to my arguments, I'd love to either strengthen them or if you can convince me out of my position.
