Have you ever seen a taxi driver being robbed and have you ever seen a taxi passenger being robbed?
This is the reason I say payment for cargo taxis is safer with Bitcoin, see what I mean.
Despite what you say, it's hard for me to see your point. Anyone can become a victim of robbery, and anything can be robbed, even bitcoin.
Have you ever heard of the $5 wrench attack? In the end, there is no foolproof way to protect against such attacks, and bitcoin is no more secure than fiat.
