No. But Riche should do what any human being should do and if his neighbor is starving, give him something to eat, etc.
But the question is not what we are morally motivated to do because we feel it is the 'right thing' or because of whatever compassion we feel for our neighbor. Such is a voluntary act and fully within our power to do or not as we choose.
The question is whether the govenor can require Riche to give a cow or cows to Pauvre or take Riche's cows and transfer them to Pauvre.
If you are the governor with the ability to do that, would you? And what rationale would you use to justify it?
Edit: Noting that Fuelrod did say "no" which I presumes that if he was governor he would not take Riche's cows nor require Riche to give a cow or cows to Pouvre. So Kudos.
We now have I think three people who have answered the question though none have yet provided a rationale for their answers.
