Physical coercion (muggers forcing transfers) is forcing fintechs like Revolut to implement time-delays and "reversible" features. Pure, instant, irreversible self-custody is becoming too dangerous for the average retail user due to physical threats. The market will shift back toward centralized, custodial intermediaries (like Coinbase) that can offer "safety friction" (delays, identity verification) that hardware wallets cannot. Long compliant custodians as the "safe haven" for retail wealth against physical extortion. "Not your keys, not your coins" philosophy remains strong among crypto natives.
