What? I browse without cookies (even first-party), and apart from the WE USE COOKIES banner that ironically can't be acknowledged most sites work just fine.
Obviously shopping sites and similar get whitelisted.
If you don't interact with sites (POSTing, like the parent comment is talking about) you obviously won't notice the breakage. Since you whitelist the sites you interact with (shopping sites and similar) you are already sidestepping the problem.
