I remember this hitting me for the first time years ago when I was playing with brain wallets, imagining myself washing up on a foreign shore like Bond, without a single possession on me, drying off and recovering my wallet with millions in it. It reminded me of how intriguing it was in movies when someone had a number to a secretive ‘Swiss bank account’. Supposedly all you needed was the number, regardless of who you were. Bitcoin is 1000 times better than this or any bank account, and I remember reading that the Swiss had to divulge everyone’s bank info anyway. Portability is key. Good write-up!
