It almost sounds like you're saying:
If I thought my life was worthless anyway then sure, throw the grenade at me.
(I'm being a bit facetious, because there is a difference between "my existing in this world doesn't produce any net good for anyone" and "my existing in this world doesn't produce any net good for anyone besides myself". But in real life, how plausible is it that we would have one without the other?)
I never thought of it that way, but you're right.
Then grenade, please! I could help more person-moments in the one Everett branch with a hundred million dollars than I could in both branches with my current level of income. And what's more, my life would be more comfortable, averaging over all my person-moments.
Really? Can't I just make a deal with Fred, pool our finances and distribute our quantum probability of life in proportion to our financial contribution?
Or, reading again, are you referring to maximising "p(life) * money_if_you_live"? I suppose that just relies on trading with people who are desperate. For example if Fred requires $1,000,000 to cure his cancer and has far less money than that he will benefit from trading a far smaller slice of quantum_life at a worse price so that his slice of life actually involves living.
Incidentally Fred's situation there is one of very few cases where I would actually Quantum Suicide myself. I value my quantum slice extremely highly... but everything has a price (in utility if not dollars).
That's why you always make sure you're the house.
By the way, underscores work like asterisks do. Escape them with an \ if you want to use more than one.
Fair systems are good for the person who would otherwise be exploited. They aren't good for the one who is seeking advantage. The whole point in this branch is that you were considering the availability of finding deals that give you positive expected returns.
If you are looking for a way to ensure a real positive expectation from a deal you don't create a stock market, you create a black market.
