That comment was intended to be read somewhat tongue in cheek, but for the sake of argument:

1) What's the point of having money if you aren't going to spend it and have fun? I suppose you could throw a smaller party and write a big check to the Google Philanthropy...but either way money is meant to be used.

2) If you actually had the skills and personality to turn $20K from YC into $3M in three months...you've clearly got entrepeneurism in the blood and shouldn't ever have trouble finding a lucrative job that you enjoy.
