Unfortunately you need cookies for any good user analytics; and no, I don’t mean the invasive kind that Marketing put in - I mean the kind which allows you to figure out why your site is broken.
Which ironically are the same tools you’d need to find out if your users are experiencing unintentional dickovers.
Cookie banners aren't a force of nature. They are required solely because you want to track people. Not tracking people? No need for a cookie banner!
