Because filming on these cameras sucked. They were noisy and require shitloads of tape. Now they are not as noisy. But you see that the roll weights 400 kg, too.
Nolan is one of the few who can pull such a demand for equipment, but the theaters are not going to order expensive equipment for 1 movie every several years at best.
But projectors and cameras aren't especially linked. Movies can be shot on IMAX cameras and only released digital, or filmed on digital/70mm/VistaVision (and so on) and be released on 70mm IMAX. The main reason is the costs.
Of course you can film digital and show in cinemas on 70mm, but you will not get any of the supposed quality. Similarly with filming on 35mm, the improvement is there, but not as much to make it worth.
70mm projectors only make sense if the movie was filmed on 70mm originally.
They do. Alexa 65 is just one such example. It is already specialized for wide aspect ratio of over 2:1, but with anamorphic lens you can squeeze to get the same 2.76:1 or similar

If they want us to watch Imax so badly make more Imax theatres man. We don't have single true Imax in my country. And that's true for most countries.
