Sure. That's why I'm not too big a fan of security. The flip side of your observation is this: the most secure form of computing is a rock. You can ensure users can't be pwnd and can't selfpwn themselves by making the device as useless as possible.
Let's give every user a tablet that has two buttons. You press one, you get a new cat picture. Press the other to "like it". That's all the user needs. All data exchange is end-to-end encrypted from the cat picture provider to tablet's input&video drivers - can't risk the spooks^Wcompetition knowing what they're looking at. They don't need to do banking - like everywhere else, they just sign a three-party contract with the tablet provider and the bank. This way, the Bad Guys can't steal users' money! Oh, the users also want to watch pictures of squirrels? There's a separate tablet for that pulling from separate provider; it's insecure to let these mix on one device!
Seriously, this is how the world would look like if security got its wish. There is a point past which security is essentially enslavement, and that's true both in physical security and computer security.
