I'm bothered by the intertemporal implications of this, i.e. if I have $100 that I will spend to help the most humans possible, then I could either spend it today or invest it and spend $105 next year (assumed 5% ROR). Will I then ever spend the money on charity? Or will I always invest it, and just let this amassed wealth be distributed when I die?

The good you do can compound too. If you save a childs life at $500, that child might go on to save other childrens lives. I think you might well get a higher rate of interest on the good you do than 5%. There will be a savings rate at which you should save instead of give, but I don't think we're near it at the moment.

Or, of course, go on to harm them. Or be neutral. It seems almost certain that on average there is some benefit from the standard trade and comparative advantage reasons, but I have no idea how to even approach that calculation.
