answers to your questions

(These are my own opinions only )
#1 - no
#2 - yes
#3 - not applicable, since answer to #2 is yes
#4 - no

I think #1 & #2 are self-explanatory; as long as you can find somebody else to raise the child, then you should not have to. But yes, if you bring a child into the world, you have a responsibility to make sure it is cared for.

The distinction with #4, in that instance, it was not the adult passerby who created the problem. While it would be deplorable for the person to ignore the baby, the libertarian view would not raise it to the level of "crime" where you should now be punished by society, i.e., failure to remedy a problem that you did not cause.
