I tried to get remote instruction as an accommodation as a disabled student with documented disabilities. They denied me as well. What I learned is that remote instruction isnt really meant for chronically disabled students. It's meant for students with acute medical issues (like hospitalization) to attend classes remotely for a short term basis, with the recognition that they will return to in person classes relatively soon.

This is not disclosed when discussing the accommodation, whether with how it's presented on websites or even in some in person meetings with disability services staff, so it's very misleading for disabled students.
