Hunting people for sport
I'm curious about how this hypothetical scenario would play out in your ideal society:
A man recently lost his job. Let's call him Dave. Dave can no longer support his family and they face homelessness and starvation. Fortunately, this man happens to run in to Ellen Muscato, an ultra billionaire famous for their vast wealth.
Ellen asks Dave how they're doing and Dave explains his situation. Ellen, always the philanthropic type, offers Dave a deal:
Ellen will pay Dave's family $2 billion if Dave allows Ellen to hunt Dave for sport. Ellen also assure Dave that each of his kids will also get a $1 billion trust fund. After the hunt, Ellen will taxidermy Dave and put him in his trophy room in one of his mansions.
They find a lawyer and draft the contract. Then Ellen goes on to drop Dave off in the jungles of Brazil with adequate food supplies and the hunt begins. Ultimately Ellen kills Dave and has his body taxidermied and placed in his trophy room as per their contract.
Is this acceptable to you? Is it logically allowable under your preferred society? Why or why not?
EDIT: I'm particularly interested to hear from right libertarians. But I do want to see how all the different systems would approach this problem.
