"HTML, by default, is accessible" is at best a massive oversimplification. Arranging react elements in a certain way can break them. If you're writing out <div>s and tables like it's 1999 then sure, I'll take your word that this usually works with screen readers. But it's not 1999 anymore. It's a non-trivial task to make a modern website accessible to screen readers. My past workplaces had dedicated accessibility teams ensuring that the site and mobile apps were usable with a screen reader. The point is that "websites are accessible to the vision impaired by default and it takes extra work to render them inaccessible" drastically trivializes the work it takes to make a moderately complex web accessible. And it falsely accuses those who don't have the resources to do this of deliberately making the site inaccessible.
