the lack of parent (and most pet) licenses is how we have so many people with long-term trauma or fucked up lives due to bad parenting... like 99% of people make terrible parents. imo you should at least have to pass a few courses related to parenting funded & certified by the government to possess children or pets, or even pass some sort of psychological examination. it's extremely important that people who aren't fit to parent don't have kids, that's how you end up with... the average first-world person now (humanity is in a terrible state right now so that's pretty bad). it is a "slippery slope" to government do bad thing, yeah, but that can be said of most restrictions and it's up to us as a society not to fuck that up.

that being said, our current society is NOT able to properly handle the responsibility of anything of the sorts, everything i said doesn't really apply with such corrupt and immoral governments where literal fascists have a fine time just waltzing in. and it probably won't ever apply unless we somehow purge all fascist scum from power and don't let them in again (not happening in this reality). at least in the US and some of Europe looking at how the governments are completely screwing child & potential parents' rights it gives a pretty clear idea of why it's a bad idea otherwise (gay couples can't even legally adopt in much of Europe, including Italy & Switzerland).
