Antinatalism

It's not.

Then there's no justification to call it a crime.

At exactly what scale does it cause harm?

At a global scale. Total economic collapse within a couple of decades.

This is not well thought through. If lots and lots of people really want to have kids, that does not give lots and lots of people the right to inflict harm.

It's not about "really really wanting to have kids".

If someone chooses not to have kids because they're antinatalist, that inflicts harm on zero people.

That's not true. Other people's children are going to pay for their wellfare.

That doesn't change if it's two, or three, or 7 billion.

That particular thing, no. But when applied on a large enough scale you will see a huge impact on the economy and it will eventually crash and burn, most likely within a couple of decades.

If it is made illegal to have children, that's slightly different. But not by much. Making it illegal is based on the idea that you don't have a right to do that - to create people you know will suffer. Just like you don't have a right to punch people, even if you really want to.

It could be made a crime, sure, but there is no justification for it, because it would be based on a contradiction.
