We could live in a world where there was no injustice visited on Native Americans and Ayn Rand still either was or was not a hypocrite about Social Security. But I think Rand neutralized that by putting it in the context of losing money via taxation and recovering it as a benefit.

What's essential to that argument is what's contained in Rand's philosophy about taxation and her personal actions in electing to receive the benefit. Broadening the scope of the argument to include Native Americans in order to sustain the charge of hypocrisy is an indicator that the Social Security argument is not able to stand on its own.
