Aggregated analytics do, and you can't run a serious website without some kind of analytics. Preference-storing does as well, despite any reasonable user expecting that, if they set a preference, it will be saved.
You don't need cookies for basic aggregated analytics. Now if you want to track and record mouse movement, you do, and that's a privacy concern.
The law really has nothing to do with cookies, it has to do with privacy, tracking, and PII. You can absolutely save preferences and perform analytics. What you can't do is hoard data that is personally identifiable for purposes that are not obvious to the consumer.
There are many analytics solutions that dont require cookies. You can do aggregated analytics just fine without. Saving preferences does not require consent either.

Good.

I don't believe you.

IANAL, but I'm given to understand that this is untrue.
