In any place of the world Id be totally against it. Although it might be a bit extreme its a *legalized and modernized" system for slavery.
If you put a price on humans body you're going just back to slavery and people will start selling their bodies.
Imagine a husband with a lot of debts, what'd stop him from commiting suicide and then earn some profit to pay the debts? It'd surely look interesting for desperate people.
Funeral expenses in the other hand might be nice, since you wont really have any gain or profit that'd give you the chance of even considering it.
Any sort of incentive that could benefit the family with their problems would be horrible with the only exception of funeral expenses as thats something you'd have to go if you die.
