You don't need a cookie banner if you don't have 3rd party tracking cookies. It's really that simple.

The fact that all sites have them, shows us a terrifying truth: all websites are tracking us with 3rd party tools. "all" websites send our browsing habits off to (many) companies that will sell, mine or otherwise monetize our data.

Again: A cookie banner is not needed if you don't have 3rd party and/or tracking cookies. E.g. With matomo on your own domain, plausible analytics, or simply mining your servers logs with math, you won't need cookie banners.
