Crypto, on the other hand, seems to be predicated on retail investors and consumers. So they do seem manifestly different as you have expressed them (maybe my issue is with the notion of the "average" VC-backed company?).
By design the average VC tech company (the 49) is a flaming failure. That doesn't mean they can't be packaged up and sold.
Crypto only has "Bitcoin has above market returns" in terms of success.
There was some neat smart contract stuff but some of that technically breaks trading rules (aka is questionable legality) and others are a coin flip as to whether a vulnerability will let someone drain the entire fund.
It's not all "number goes up"/a zero sum game of early investors selling to later investors.
Ethereum is equally successful.
To take it even further, what provides more value? Instagram or OpenSea (NFT marketplace)?
When you stop and think about it, it's the Spiderman meme. They are both pretty useless and are most likely a net negative to society.
OpenSea was only profitable while there were still suckers available. Not at all the same.
Instagram is more like Exxon or something. A very profitable enterprise whose social harms may not be adequately internalized, and would require legislation to fix.
There's a ton of cool tech that provides a ton of value and makes little to no money.
