Out of What Bodily Orifice Did They Pull That Figure?

The latest protest by the left-wing division of Nuts R Us features the following:

To this end, we now make our first clear demand of Google. We demand that Google give three billion dollars to an anarchist organization of our choosing. This money will then be used to create autonomous, anti-capitalist, and anti-racist communities throughout the Bay Area and Northern California. In these communities, whether in San Francisco or in the woods, no one will ever have to pay rent and housing will be free. With this three billion from Google, we will solve the housing crisis in the Bay Area and prove to the world that an anarchist world is not only possible but in fact irrepressible.

Why three billion dollars? Why not Skewe's number or Graham's number? Why not ∞? Why not \(\sqrt{-1}\)? It's just as imaginary.

By the way, what's stopping them from creating their own communities without subsidies? I understand there's plenty of vacant land in Detroit. Detroit is what happens when ‘parasites’ leave.
