That’s like saying the killer app of the internet is the internet.
The web gives me access to information quicker and easier than going to a library or bookshop. Email and IM means I can communicate with people in other countries quicker and easier than I could by post. Crypto doesn’t change anything.
A few drug dealers and some people living in countries with hyperinflation may care about “permissionlessness” and “censorship* resistance”, but for most people, actual money is far, far more convenient.
* That’s some Orwellian newspeak, btw. If someone defrauds me and a court of law ensures that I am restituted, the reversal of that fraudulent transaction isn’t “censorship” because stealing money isn’t “speech” or “expression”.
