There's really not a need to. Others have pointed out that your ISP might inject ads, or something similar, another thing is encrypting only the traffic you want to keep secret leaks information about the fact that you're doing something you want to keep secret.

These are not issues that are likely cause great damage, so no, there is no need to encrypt every last bit of traffic. But the bigger question is "Why wouldn't you encrypt it"? There's really not a lot of reasons not to.

Your argument, out of everyone else's, is the most sane. So lemme point this out:

> But the bigger question is "Why wouldn't you encrypt it"?

You're right. There's not a lot of good reasons I can think of. The best argument I've been able to come up with is ISP-level caching of HTTP traffic, which may save on bandwidth. But my host doesn't even charge for the measly amounts of bandwidth I use, so that's certainly not a concern.

Modern servers have HTTPS hardware-acceleration in the form of AES-NI, so it doesn't even use much more CPU power to use TLS these days.

So really, bandwidth savings from ISP-level caching is the best counter-argument I've got. Which is to say: not a very big concern of mine.
