> You don't need cookie banners; they're only mandatory when you want to track your users, so when you see one of those on every website, it just means every website wants to track you.

Why does the European Commission's website want to track me? They have a banner, too. In fact, I have yet to visit an EU government website that doesn't have a banner.

It would be so much easier to make the websites honor "do not track" settings in the browsers.

So they are mandatory, since all websites NEED advertising revenue and analytics to function.

No, some websites can just sell a product or serve some business function, and don't need tracking at all, yet usually have it anyway.

The one you're at right now seems to be doing fine without ad revenue.

analytics are fine as long as you use GDPR compliant anonymision of the users data. But it’s easier to just ask permission.

You can also run ad’s asking as you are not using targeted ad (which you are allowed to use if you ask for permission)

There are invasive ways of asking for such permission. Sites that do full take overs of the site or persistent bars that follow you around are just trying to annoy the user into clicking agree.
