To be fair, the idea of "alternative to banking" is still very much alive. BTC and LTC are very much used as currencies, even though BTC has fees too high for small transactions. Monero was developed specifically with utility rather than investment in mind - now reading about how exactly anonymity is enforced there (especially after the Chainalysis leaks), it's pretty interesting. I kinda hope we invent something better than blockchain-based currencies that is equivalent in uncensorability, but right now it's the closest we got.
