Some people tell me that Parecon can’t be realized on the grounds of Arrow’s impossibility theorem and Gdel’s incompleteness theorem. How to refute it?

I’d probably just laugh. I mean, really, you just gotta. Arrow? Who? What? Really? That’s hilarious. Gödel’s theorem? Seriously? Really? That’s even more hilarious! Well, if they say so! Shit! What’s an idiot non-logician, non-mathematician like me to do, huh? My stomach hurts. But then again, maybe…

this statement is false!

Has no relevance. There are much better criticisms of ParEcon than that.
