Afterlife Overhaul?

[Piper Juunanagou]

Wouldn't it be better if these things were just coins?

I mean, I think the concept of karma is interesting, but wouldn't it be a lot simpler to execute the original idea (afterlife-specific shops for dead people to enrich their experience, yadda yadda yadda) if they're a simple currency, rather than vague, philosophical values? Then there'd be no need to do math or discuss the cosmic morality of the character. =/
