What if you want $4B so you can finally end homelessness, or really contribute meaningfully to cancer research, or ending mortality? These are "shaping the world" that aren't possible for someone with a measly $10M, but might take billions to achieve, as well as aligning political actors (who require donations). "Shaping the world" doesn't have to be a bad thing, that's what we otherwise call "civic duty" when we try to shape the world with our votes.
