There’s no reason to do away with active glasses in projectors. It’s by far the lowest bar to entry for 3D on any device made after 2017. I definitely agree that if we could get new 3D TV’s, it would be great to standardize around polarized glasses (or autostereoscopic lightfield displays.)

There's no need for a second projector as there are projectors that are able to do that with single equipment.
And about those prices... if they are expensive that is because the demand is low and they tend to have high prices. If people buy passive TVs or projectors then the prices go low because the demand makes technology cheaper.
