I know it doesn't help "the 99%", but you can set up your browser to block cookies by default and always block third party cookies.

What I've found is that a small subset of sites don't work without third party cookies (PlayStation store login being the only one I care about) and that a lot of sites don't expect localStorage access to ever fail (eg Codepen, I've had to fix some of my own sites that assumed localStorage access never throws).

The oddest issue I've come across was that LiveJournal would use JavaScript to immediately reload the site if a cookie wasn't detected so I had to disable JavaScript for all of LiveJournal to stop it from getting stuck in a reload loop.
