Spot on. Developers/tech savvy people have hundreds of passwords for all their services. The serious ones use Keepass or similar to store the passwords, and don't have a problem. The "normal" computer user does not have hundreds of passwords. They have a few. And they give them all the same password, or similar enough. They don't have a problem remembering them, because they're simple, easy-to-remember passwords (e.g. that can be cracked). Is this a good situation? No. But people don't know it. And implementing a whole new system to solve a problem that most people don't know about is simply not going to help.
