Eldians have the power of gene editing to improve the genepool and reduce suffering, disease, crime, etc., and can use resource creation for resource abundance (iceburst stone was said to be created by the FT) Zeke's point is not entirely without merit. With the power of the FT's gene editing, it can prevent people prone to depression from ever having to brought into the world to suffer needlessly.
I've seen some suggest that Eren wants to disconnect Eldians from the paths.
Why would any sane Paradis supporter advocate for throwing away the tool capable of taking control of the genetic gamble that is birth? Letting unqualified, unlicensed people to continue reproducing? Just think of how much suffering you could reduce, of how many cases like Zeke and Reiner you could prevent if you finetuned the genetic code of Eldians to be mentally more resilient and to be able to handle the struggles of life more effectively.
