Most cookies are used to store session IDs. For example, the Evil Google Cookie only stores a longish session ID.

Next, currently cookies are easily scoped - by their domain. How do you propose to scope session IDs?

Scoping by fqnd and browser session or fqdn + 1 day/week max.

That would be sufficient to limit abuses.

Won't help at all. For example, if I place an image from http://google.com/someanalytics on my page and you have a session ID for google.com domain then you'd still be tracked.

And of course, I personally _want_ lots of my sessions to last more than 1 day or week.

And lastly, nobody stops you from deleting cookies every day or restricting them in any way.

No, because if one gets intercepted, that cookie is good for years.

Use RequestPolicy and don't let J. Random Website force your browser to communicate with any other site. Saves bandwidth too.

So? If someone intercepts your session ID they'd still be able to access your data for the duration of the session.

You are free to do that with cookies.

Dear god no, don't put "easily" in the same sentence as cookie scoping. Have you actually looked at the ghastly ad-hoc spaghetti that govern that? It involves hard coding pretty much all the TLDs, and that's just the beginning of it.

Oh, sure, "easy". Until you read sections 5.1.2 regarding canonical host names, and 5.3.5 (which I think "job" was referring to) regarding the ever-varying list of "public prefixes" requiring special consideration--without which any random example.com could register a cookie for "com." and have it scoped over nearly all commercial websites.
