- Nearly all commercial websites advertise their site in some way

- Nearly all websites people use day-to-day are commercial

- To run ads in a post-1997 world, you must have a conversion pixel because ads aren't sold by impression, they're sold by clicks and they need to know someone made it to your site

- Therefore, some form of tracking cookies (oooh evil) are required

- Big Tech (Google/Meta/X) controls 99% of the real estate where ads can be run, so... they will know about visitors

Unless browsers simply had a setting by default to only save cookies past one session when users allow it. That would be a wildly more effective and efficient solution than forcing every single random website to implement some byzantine javascript monstrosity which attempts to somehow inhibit other JS it doesn't actually control from dropping cookies -- something that the JS API in a browser doesn't even support.

I work on a product that doesn't even have any ad traffic land on it or want to do any tracking, and setting up a cookie management platform was insane. You have to dive into the docs of every SDK to try to figure out how this particular SDK can be signaled to do the GDPR compliance things.
