If you are abled & find providing alt text & image description to be a barrier:
Disabled people are routinely asked by our power structures & by abled people (even our friends/family) to go through additional physical, mental and emotional barriers daily.
So if you think this small barrier of being asked to provide equitable alt text keeps abled ppl from doing things, it's good to extend that thinking to the ableist way our society is constructed & what the effect of that is on disabled ppl.
