What an obnoxious piece of drivel.
"Any application that could be done on a blockchain could be better done on a centralized database. Except crime."
The HN California tech-bros could be forgiven for not "getting it" 2 years ago. However, when leaving your own damn house became a crime, this lack of understanding is beginning to become infuriating.
The value proposition of cryptocurrencies is not only in shielding you from the whims of bureaucrats that are in charge of monetary policies, but of idiotic changes to all policies.
When my country was in a full insane-mode covid lockdown, no centralized database helped me to get a haircut. That haircut guy took only cash or crypto.
When the next insane demand is inevitably decreed upon you, maybe cash won't do anymore either.
