I see all these arguments about peaceful parenting and how parents have all these obligations to children. Yet I never see any mention about the obligations children have towards their parents.

What incentive is there for parents to have children if there is nothing to be gained from it? The way all these discussions are framed is that everything flows to the children and the children get treated like kings. If you create a system disincentives something, then you can expect to get less of it. Is that the goal, to eliminate children from the world?

The only consistent position I have ever seen is that children are property of their parent. The parents created them from nothing, which is the basis of the homesteading principle. Every other example of property acquisition is lesser than creating something yourself, so if children aren't owned by their parents, then all property ownership is brought into question. Allowing a community to dictate what a parent can or can not do is the entire basis of communism.

Once you accept that children are property, then you can better understand peoples behavior towards them. An owner doesn't damage his own property, since he's only hurting himself. There is a disincentive for people to crash their cars or burn down their own houses, since they are depriving themselves of their own property.
