As an example of a tech, if someone asked me would you want self driving cars to succeed if you could not profit off of them, I would say that's a resounding success. A lot of people are excited about this tech because of the improvement in their daily lives, not because of a profit motive. Compare that to crypto
1) I would want Amazon-like businesses to succeed -- in the sense of "someone who finds a sustainable way cut the fat out of retailing" -- even if I could not profit as a shareholder. But I still think I would benefit (as a buyer) from that success.
2) I would want decentralized, arbitrary-money-printing-proof cryptocurrencies like Bitcoin to exist as a shield against governments that inflate away their money (like Venezuela or Zimbabwe) or abuse their central bank status for bailouts (in the first world), even if I could not profit as a holder (sorry, HODLer) of the currency. But I still think I would personally benefit as a prudent saver and (non-politically-connected) investor.

* To those people who say, "You can't compare crypto to a company because companies pay dividends," that is specifically why I chose Amazon as an example, a stock that does not pay dividends.
