wrong. you can write all you want, 4k and 8k video does not come for free but causes significant additional cost compared to a stills camera.
And to repeat, i don't want an unrealistic camera, but [in addition to all the "hybrid" cameras] at least *one* realistic, pure stills FF camera with 35-45 MP, 6-8 fps, good DR, without any video/audio clutter (except internal low rez feed for EVF), at an affordable price - e.g. 1999
yeah, sorry that camera doesn't sell these days, not even for the just the exclusion of video but the stills specs are lagging too much.
the only hardware difference between video and fast stills - is the encoders.
you need extremely fast sensors for electronic shutter anyways. you need UHS-II or CFE for fast or deep buffers.
so yes, you ARE asking for an unrealistic camera. if you want that, get an used R and consider yourself pretty much there already.
