How is advocating for a larger unconditional child credit libertarian? As someone else in the thread pointed out, it's effectively UBI for children.

Anything that might lead more towards decentralizing societal structure away from the state and quasi-state subsidized institutions back towards family units is considered "libertarian" on HN. Truly universal childcare "UBI" puts the power back into the hands of parents, rather than society taxing then lording over the head of parents as to which people are allowed to care for their children with it, just not funded in a libertarian manner. This is seen as a reduction in the power of the state which is a libertarian aim.

So we've come to a crossroads where something profoundly un-libertarian is viewed by the anti-libertarians as libertarian because it incidentally achieves some of its aims.
