2,000 bucks is a lot, I know the rule of thumbs is like 3 months net salary to keep for bad days but that's just hard for people like most on HN that are young, trying to either bootstrap a business or have a ton of student debt. Not sure what I would do but I think I could sell enough non-essentials to make up the money if it was a really bad situation.
I have trouble seeing 2K as a lot: I don't think it could cover real emergencies (losing a job, emergency in my family overseas...)
