1) We are all here dealing voluntarily with a super-volatile currency because we think it will take off. Everyone is going to have a bitcoin account in this speculative future.
2) Have you really never seen 'Cops' or read a newspaper? You don't get caught by being smart... Plus, once those idiots who are "destroying bitcoin, coin by coin" wreak their havoc, .05btc will be like, 2% of the whole bitcoin economy. <---(This is a joke)
3) See #2
4) Hopefully this future-app in our speculative-future here wards off this future thug with its futuristic dummy account, but please refer to numbers 1), 2) and 3) regarding that future thug beating you to a pulp.
1. Why does everyone need to have a bitcoin account for it to be a success? Far from it. One percent adoption would make it a booming success.
2. You missed the point. The mark's Bitcoin wallet might be nearly or completely worthless and he has ten different bitcoin wallets.
3. You missed the point. Muggers are in a hurry.
4. I don't HOPE that theft protection schemes will be built into bitcoin applications. I KNOW they will be. You assume that only apps coded by stupid people will be popular?
5. Homeless muggers will understand all these things better than you, and that will inhibit bitcoin device theft.
