Venture Capitalists are much less ambitious than their private equity siblings

There is one more point I would add to the list. VC's seek high volatility experiments because the power law approach to investing means their wins have to be massive rather than just double or triple their money. VC's themselves use a portfolio to dampen volatility. Peter Thiel is on record that most VC's think about it all wrong and should just admit to making huge bets.
Rob Hayes, of First Round Capital, once said that VC's sell a product (money) to customers (entrepreneurs). This would make LPs their suppliers. If so, then having a family office, or other patient capital, back your fund would be a huge advantage.
