Not at all, you can freely walk into most exchange offices. Theoretically an armed robbery of exchanges and payment processors would be the perfect crime. Commit private address to memory or tattoo it on yourself in code, after the robbery forcing them to transfer to your public address and waiting out confirmations turn yourself in to the police and do the 5 yrs. Walk out with millions worth of bitcoins on your arm. (Penalty here is 5yrs, unsure anywhere else). Blockchain.info would prob nickname that address "Hans Grueber"
