I am also a business angel, funding people's things ever since 2004.
And this produced how many million user products?
I have produced (one as a co-developer) three separate "million user" level products since 1980s. With a lot of goofing off vacation time in between (mea culpa).
Your stance is fundamentally incongruent with the open source movement. Open source projects will spawn more and more granularly (smaller teams) and stored capital and top-down organization will become more and more irrelevant.
This is a virtual new economy; we only need to click a button to make an investment. We don't need to travel across the world. And we don't need to invest everything in one thing or two things, thus we don't need to know all the answers before the questions can even be asked. Creativity spawns serendipitously not as planned (even my own work lately proves this is true, because I didn't plan all the ideas I discovered along the way).
Open source is the odds of large numbers.

Eric Raymond noted that is the only known positive-scaling law in software engineering, i.e. that efficiency improves the more
autonomous N actors involved. Design by top-down grouping or committee is not the same scaling law.
We don't have time to waste on top-down bureaucracy.
Warren Buffett doesn't do angel investing, because he wants to evaluate companies based on
well established metrics. Angel investing is a game of more risky probabilities. Thus efficiency of scattershot is more important. Angel investing will become less and less like an exhaustive evaluation and more and more spontaneous and small, e.g. KickStarter. Everyone gives a little bit, not one big whale slowing everything down.
The Knowledge Age is the end of the road for large stored capital. The power-law distribution of wealth will shift to stored knowledge. Actionable knowledge will be power-law distributed. It already is. Which is why when you are searching for a needle in a haystack, don't tell the needle to jump to your castle.
It doesn't matter if Paypal accepts Bitcoin because users who are not investors (e.g. especially females and the billions of impoverished) have no incentive to convert from their unit-of-account (dollars) to BTC just to pay for something. They might as well just fund their Paypal transactions with their credit card or bank account. Bitcoin will not become the unit-of-account without the blessing of the government, because it has no distribution scale.
Most of the impoverished don't have a credit card nor bank account.
The Paypal plan.
The reason Paypal couldn't just issue everyone in the developing world an account is because of jealousy thus legal and political risk. Governments would resist take over of their financial control by an overtly fascist corporation.
Peter Thiel et al are more clever.
Issue everyone a supranational digital account that is "decentralized and controlled by no one", when in fact it is centralized and controlled by the fascist powers-that-be.
Use this to force other countries into submission when they attempt to offer their own top-down centralized digital currencies, e.g. Ecuador.
The people are trapped either way in a fully traceable block chain and NWO Technocracy.
Monero (portmanteau of money+dying euro?) offers no hope of scaling to avert this rapidly developing fascist outcome.
C'est la vie. Fait accompli.
And the competing and equally devastating
Apple Plan.
