The problem is that regular entrepreneurs and business owners still must share the market with venture backed startups. You're always one pivot away from some hotshot startup or bigcorp going to war to take away your marketshare by forcing you to address that "the market can remain irrational longer than you can remain solvent" -- in order to compete with VC-backed startups, you need /more/ than just frugality. You need actually better execution -- execution which more effectively serves market demand than your competitors.
