The argument for "you can't consent to being born" does have a direct opposite argument: you also can't not consent to birth. The birth is what gives the ability to consent or not in the first place. You could argue that by being anti-natalist you're taking someone's potential to give consent completely away, which is the same or more unethical, you're essentially deciding for someone else that they should die/not exist without them getting a say in it?

You can do the same with suffering: life is happiness, everyone I know was happy sometime in their life (even if only as a child), so you're doing serious harm by not allowing people to have happiness since only people who exist can be happy.

I think anti-natalism is a philosophy mainly held by very traumatized people and/or that live in very bad conditions.

We know (roughly) how to handle trauma, we know (roughly) what makes good conditions. We know roughly what makes people happy or what makes them suffer. We have the potential to create a world where being born is mostly positive for everyone.

In that sense, currently, I think mostly people that are well off should have children, ones that can actually support children properly. However, that is obviously not a permanent solution, since the end goal should be for everyone to be well off and to be able to support children.

But part of the suffering in the world is also caused by too many people. We can't have infinite population growth while living in a world with finite resources. As such, we need to limit how many children people can have (which is already happening by availability of birth control and smarter people, able to make a choice if they want to have kids).

So in total, I don't think birth/existence is either good or bad, but it has the potential to be both depending on how we handle it.
