Perhaps but you're talking a year or more of building. Also, while there are plenty of Muskboys on HN, I don't think he has the star power that guarantees success, so it'd have to be something more than just "Twitter without moderation", resulting in a pretty long lead time to alpha v1. More likely he would just buy a different platform, since many of his companies he hasn't created from the ground up.
