We do not agree.
But obviously you have a problem to understand the sentence I wrote above with the invitation to ask questions in case of trouble to understand. So why not ask questions?
I said that DR is a function of spatial frequency. This is totally diferent from saying that there is a trade of between DR and resolution. A trade of suggests a choice to be made. There isn't. A digital sensor records an image at
all spatial frequencies up to the limit given by the pixel pitch. Its DR is a function, not a value.
What you believe is like saying to an audio engineer: Please, cut the recording frequency at 1kHz because I don't want it to become noisy.

Not true.
If you read my paragraph about the ideal camera above and add a little margin to avoid clipping the noise, you'll see that a sensor with about 10 trillion 1-bit pixels at ISO 100 would just work perfectly.
There are no whole black or whole white or even whole grey areas. Just nicely dithered due to the shot noise. This thought experiment doubles as a great explaination why shot noise is inevitable too: How could the number of photons ever match exactly the number of pixels in an area of the sensor?
Why is it this hard for you to step back and try to think over your proposition?
I think I've now done my best and give up at this point. In case you ask a sincere question, I may well still try to answer it though.
