That's why I didn't just assume your need for a billion dollars was automatically greed.
But you still presuppose a general quantification of what constitutes need. The fact that you tried to trivialize the scenario by referring to it as an example of prerogative proves that.
It's not a matter of prerogative that I need a billion to dollars to maintain a billion dollars worth of living conditions. After all, I couldn't dos such a thing with less.
And you still haven't established your own parameters for "need".
