She considers wealth redistribution as something that causes people to sacrifice their wealth. She also considers rational self-interest as something that can't happen if others sacrificing anything. Thus voluntarily participating in an act of wealth redistribution, which getting social security is, contradicts rational self-interest because it's causing others to sacrifice their wealth. Her doing that either means she's a hypocrite who doesn't actually believe in her own work, which you disagree with and defend (as evident from the very first comment you made), or her work is ideologically inconsistent, which you also disagree with and defend (the comments where you argue it's in her self-interest because she's paid into it).

It doesn't matter to me which way you're going to try to twist this, you're going to end up defending her or her ideology because you've already done both of those things. I'm not going to continue arguing over those points because I've already established my surrender. You won the defense of Ayn Rand, hence the tag.
