I think something like store.js ends up being genuinely useful for anyone building functionality that depends on localStorage. More often than not you find yourself either having to deal with issues that store.js solves for you (E.g not breaking your site in Safari private mode) or requiring extra functionality that already exists as a small store.js plugin. (E.g expiring keys, default values, etc). All of these are things you can of course do without a library, but at that point you're reinventing the wheel a bit and not benefitting from all the automated testing that ensures cross-browser correctness. With that said, I agree there are times when just a quick read/write directly to localStorage can be the right call, but by default I think it comes back to bite you one way or another more often than not :)
