Saying web users should define web standards is like saying laptop users should design CPUs. They lack the expertise to do this meaningfully.

Web authors? Maybe. WHATWG was created specifically because W3C wasn’t really listening to web authors though.

I don’t think there are a lot of scenarios where standards aren’t driven by implementers, though. USB, DRAM, WiFi, all this stuff is defined by implementers.

Ask users what they want and they say "faster horses," not cars.

Users are a key information source but they don't know how to build a web engine, they don't know networks, and they don't know security; and therefore can't dictate the feature set.

web users make their choice via choice in browsers.
