That is a normative framework of what type of permutations of reality should be considered “normative”
Disabled people are humans, they are people. Let them play with the fantastic. Some disabled people would do as you described, but others know that a normative framework can be dispiriting and disheartening. Figuring out alternatives such as a combat wheel chair is about reheartening the tender heart and reclaiming agency. To except there are many ways to live and how a normative ideal can be an illusion that makes some people miserable.
Representation matters. We create mental models, we humans are mimetic creatures and recognizing there are many ways to succeed and how storytelling mimetics, storytelling imitations / acting is literally how children and adults play. Children’s play dolls all the time, it is how they help gain later skill sets. Now imagine a person in a wheelchair their entire life and they never had a doll of a person in a wheelchair. It is not just aesthetics, it is something more than that, that words find hard to articulate for it is not about description and narration, it is about showing and living as a subject not an object. Different part of brain not language but more visual more action.
