Why would someone flee libertarianism and become a liberal?

[★Ŕ♡MΛŔƐ★]

Interesting personal story. Here's part:

I began to think about real people, like my neighbors and people less lucky than me. Did I want those people to starve to death? I care about children, even poor ones. I love the National Park system. The best parts of the America I love are our communities. My libertarian friends might call me a fucking commie (they have) or a pussy, but extreme selfishness is just so isolating and cruel. Libertarianism is unnatural, and the size of the federal government is almost irrelevant. The real question is: what does society need and how do we pay for it?
