>There is an interaction-free solution; it's called 'do not track' (as in, not tracking users). The EU don't mandate it
If it's not mandated it's not a solution, it's more like a pacifist asking for peace in the middle of WWII
>The EU don't mandate it, since that would probably be considered over-reach
I don't think that's the reason, as it wouldn't be any more overeach than mandating the current cookie notice (or, in another domain, USB-C for mobile phones).
That's not mandated. You need to notify the users about third parties getting their data and allow them to opt-out. The cookie notice is just a common, terrible implementation of that requirement.

They didn't do that either. They forced the relevant companies to agree to a standard until next review and the agreement was USB-C. No specific solution was mandated.

As viraptor says, cookie banners are not mandated; they're a crappy UX invented by ad companies.
In any case, regardless of one's personal opinions on user tracking, I don't understand how 'cookie notices' are at all equivalent to a flat-out ban on all tracking by anyone ever.
