Should unwilling parents be forced to pay child support if we'll have a UBI?

If a UBI is in place, then the state has taken over what a parent should have been left with to do.

That bit of (welfare state) thinking may be why we now have about 50% of all household with single parent children, --- being able to say that they are not supported by the deadbeat dads that created those children.

Not sure what statistics you are using but you are kind of agreeing with the OP.  Most of the cases of child support issues I've seen are ones where the guy has his act together and the woman uses a kid like a cheap trading token to extract money.

It would be interesting to have a world where child support payments were actually that vs women enrichment payments.  It never made sense to me why a woman who has never had a proper job is entitled to millions simply because she slept with a man who is wealthy.  That is basically state sponsored legalized prostitution... except it is more expensive.

In other words, the current child support system is either excessively punitive towards unwilling parents or insufficiently pro-children, depending on exactly which perspective one looks at this issue from.

In all circumstances it is insufficiently "pro-children".  There is no monitoring of the funds that go to the custodial parent to ensure that the child is actually the one receiving the benefit of the money.

I have a hard time seeing child support as anything other than an unnatural compromise between two worldviews - one accepting that people have the right to live their own lives, the other imposing on parents the social responsibility of raising their offspring.

I voted No.

Writing a check is not "raising their offspring".

Point Of Order: Child Support Payments as we know them have nothing to do with the well being of children. The program solely and exclusively exists to save the state money they fear they otherwise would have to spend to subsidize the needs of the child.

This.
