You're assuming everyone is rational. For instance, if I were a future billionaire I'd totally do it... knowing I'd never see even a glimmer of return on the investment... just cause.

Yet how many billionaires on earth do that?

I guess once you have the money you also develop a sense of responsibility about how you wish to spend it. Every thing in the universe, even if we imagine unlimited resources at one's disposal- Every project has its costs. It might be time, energy, or other manual resources. You have to continually trade one for the other based on the goals you have currently.

We are assuming that life forms will just build probes and let them wander for some remote chance of another life form to see it.

It's impossible to judge what one might find valuable. Preserving life as "a thing" might be just as important to future-wealthyperson as fighting Malaria is to a current one.
