Steemit actually got me interested in anarhism too. But, like you, I don't know much about political philosophy, or politics. Or economics. So, it's an interesting idea (anarchism), and aspects of it I find attractive, but it'll require a lot of research till I can form an informed opinion.

for me, there are strong philosophical/moral arguments for having a social safety net in place

Ditto. And I was a Bernie supporter as well. But I think Bernie would find fault with the way money here is split between the whales and the minnows! Steemit, I find, is not much different from the real world, so I don't think it's a good model for anarchism, as @anarchyhasnogods (from steemSTEM) will tell you, steemit is basically capitalism.

It's interesting that on steemit you'll find anarchocapitalists and anarchocommunists. Strike the 'anarcho', and you're left with good ol' capitalism vs communism! Same old debate, differently clothed. I see steemit more as a means to an end rather than the end.
