You've obviously never actually started a company. Talk to me when you have. People with money flame out every day. A huge percentage of companies that do receive VC funding fail. Way, way more than half. An infinitesimal fraction of companies VCs invest in go on to be worth more than a billion dollars. An even smaller fraction of those go on to be worth more than 10 billion dollars. Jack Dorsey created two of them. There are only a handful of people on earth who have done that. And when I say a handful, I mean like you can literally count them on your hands.

A) A "network", i.e. is friends with talented people
And has access to:
B) "Immense amounts of cash". How much cash? 1 million? 10? 100?
Can easily earn a 10x-100x return on that money? You think turning 10 million into 100 million is easy? Do you know how many people are trying to do that? Do you have any idea how difficult that is even with access to a network and cash?
Money is extremely cheap. The biggest problem in silicon valley right now isn't access to capital - it's that there's too much capital chasing too few good ideas. VCs are desperate for something worth investing in, precisely because of how hard it is to create a good company.
