> Fungibility can hardly be true for the venture capital ecosystem. Many people who wanted to invest in Facebook, Snap, Uber, etc. could not do so.
Many people who want to invest in Amazon right now cannot do so, because the shares are very expensive. That doesn't mean they're not fungible, it only means the existing owners won't sell for what you're willing to pay.
> The "buy-in" price that you mention is not efficient because some people cannot participate no matter how much they are willing to pay.
If you went to Zuckerberg in 2004 and offered to buy in for the equivalent of Facebook's 2018 valuation, would he really have turned you away?
Early stage startups are sensitive to who invests because early investors typically get seats on the board. The problem with the Saudis was not that they would use their board seats to ruin your company.
> Similarly, imagine if Uber wanted to hire a top Computer Vision researcher, and they could not. This hiring situation might not even get noticed by a LP, but an LP would surely notice if a VC was not able to invest their money in the next Uber / Facebook.
The thing about "the next Uber / Facebook" is that nobody knows who they are yet. And the number of startups who could be them is huge, even though most of them won't. Not being able to invest in a random startup that might become the next Facebook is hardly an issue when there are a hundred more that you can.
