The goodness isn’t in giving all the money away, but in the positive change you can induce while making even a fraction of it available to a worthy cause. Obviously you wouldn’t create a better world by giving your money away to another billionaire or Polluting Genociders Inc, but if you engage in good faith and steel man the argument you can surely find some examples you’d agree with, such as preventing wars for resources and saving people from painful slow deaths due to starvation. Can we agree those are positive things? That working towards improving the lives of others without expecting a return makes one a better person?

Consider this: A billionaire (not even a multibillionaire, just one on the “lower end”) who gave away $1 a second would be giving away $86400 a day. Sounds like a lot, until you realise it would still take them 32 years to give it all away, and that’s assuming they wouldn’t be making any money in the meantime.

Now consider the number of people living in extreme poverty.
