There's a recent anime called "The Great Cleric" that addresses this slightly. People with the ability to heal may charge crazy sums, and even the knowledge of spells that could help may be financially gatekept because of the wealth generated by healing.

Realistically most adventure parties leave many disabled people (and beasts) in their wake...
Couldn't a cleric heal partial paralysis tho?
In addition to the list of explanations for why disabled people can exist in a fantasy setting that chumbalumber@lemmy.blahaj.zone provided, I'll also just say:
Using diegetic explanations for why a problematic aspect exists in a piece of fictional media does not address the substance of the problem. The problem is that disability is often not represented in fantasy stories. Pointing out that there's an in-universe explanation for why this may be the case doesn't solve the lack of representation. These stories are fiction, and you can add any explanation for why disabled people exist as easily as you can erase disability completely.
This video does a good job of explaining this some more: https://youtu.be/AxV8gAGmbtk?si=YRvXjpZv_YP9Z5sC
Why can't magic cure them though? In star trek, people don't cure Picards baldness because people don't care about it, they realise its nothing to mock. But that's just a "cosmetic" ailment.
Things like blindness, or being unable to walk should be curable by magic, right?
Magic medicine means magic ailments. Just like the introduction of antibiotics produced bacteria like MRSA, the use of magic to cure wounds could produce MRSA. That is, magic resistant staphylococcus aureus, as opposed to methicillin.
Curses and other such primarily magical ailments could also be much more difficult to deal with than simple infections/wounds.
Because magic is a tool to tell stories, and you want your group to meet a blind person. Maybe you invent a kind of blindness that can't be healed by ordinary healing magic, or a social rule that doesn't allow for it to be healed, or a severe negative side effect, or whatever makes sense to explain it.
I've always wanted to have a DND character that's an armless monk and all they do is kick bad guys to death.
I think the real problem is that magic in D&D is so mundane that any problem can be "magicked away", be it healing a wound, curing diseases or exploding an enemy. That makes some situations only really plausible when it's explained as some stronger magic or "weird power" interfering with common magic.
It's a magical fantasy setting, I get it, but magic being so common and consequence free makes it a deus ex of whatever flimsy explanation you can imagine. "Why do disabled people exist in typical D&D?" Cue that meme of the cartoon's Dungeon Master "It's magic, I ain't gotta explain shit".
I really don't understand what's wrong with people not "curing all illness and disability with magic™" in a world where magic exists and is a thing.
See, in most such fantasy settings, magic not only exists but it has an attitude. Sometimes, a conscience, and not a very ethically nice one (if it allows for eg.: necromancy!). Sometimes, magic even is a god (or gods). Even if they aren't, the people who use magic are still ultimately humans (with leafy ears etc but still ultimately humans with costumes, at worst) driven by greed, envy or a weird righteous idea of how should a woman dress and behave when in public.
Would you trust some rando nutjob, who claims to speak for Evelok the Eternal Coffee Mug of Satisfaction, to up and magically conjure you new eyes, new arms, whatever? To alter your body to such a fundamental level? Normal people in such settings are already afraid to death of werewolves and those are quite normal things. Compare: even in our magicless, relatively normal world, we have the power and the money to cure most illness and to treat disabled people adequately yet Obamacare is not universal and we can not trust that the people who give people implants and prosthetics haven't backdoored them to force those disabled people into corporate servitude.
Your player party may be the goodest bois, but they're only one. The various guilds and churches around quite likely aren't such goodies on aggregate either, or else there would simply be no plot.
There are deaf people in the real world with treatable deafness that opt not to because they don't view their deafness as a disability. In addition, not all neurodivergent folks view their conditions as disabilities and wouldn't change even if there was a "cure" for it.
So, I don't see how disabilities in a fantasy setting would be different. It's not even necessarily about trusting the cure, many times it's about how folks view the condition and themselves.
I don't doubt their existence but the wheel chair doesn't look like fantasy.
In Pathfinder there is a whole subset of assistive items so that all gamers can feel welcome at the table.
Depending on the magic it might not make sense because people could heal everything, although you could explain it away by saying that the character could not afford a skilled healer.
I looked it up and the first known wheelchair that you could move yourself in was invented in the 1600s, which was after firearms became relatively common.
I'm gonna devil's advocate this for a second.
Unless you're very poor (which is fair in most fantasy settings there's always poor people) magic kinda negates disabilities.
Like is there no spell that can cure these disabilities?
With that said to have that big of an issue with it just makes you an ass
Regenerate is a 7th level spell. A cleric would need to be 13th level or higher to use this spell. They are not that common, and they likely have more important things to do.
Reminds me of my favourite Flamethrower
