I think mentioning "well if the lock's too hard they'll just break the window" is missing a point: locks right now are just too easy. Destructive bypasses to locks, or even just cutting the lock into pieces, are probably a good thing, since it prevents the equivalent of losing your Bitcoin wallet. But you want the attacker to be forced to either make a loud mess or go elsewhere. If you didn't encrypt HTTP, you could sniff packets on the network, walk through the front door. If it was weakly encrypted, someone with some level of expertise could basically do the same, pick the cheap lock and walk through the front door. With RSA-like encryption, this avenue of attack is basically closed, and now the options are more like "try and steal this guy's laptop" or "launch MITM attacks".
