They've been pushing it back every year because states haven't implemented it uniformly. Washington gave me a non real-ID card in 2022. IIRC the only real-ID option at the time was an Enhanced ID which can be used to cross the border from Canada and costs $100.

As the other comments inform you, many states were not coerced into adopting it until very recently. In these ~dozen states the majority of people do not have the new federal ID. There are Enhanced Driver's Licenses as alternatives the to the invasive federal ID but most just have the normal state ID that work perfectly well; excepting these contrived situations the feds use to try to force people with.
