I agree, but it's only marginally easier to type.
But the markdown is not the final product, it still needs to be converted to html using a "static site generator" or some other thing that breaks every couple of years. I had my static site break due to jekyll shenanigans four times in the last few years, and then I decided to move the whole thing to plain html, and replace jekyll and its myriad of unused and fragile dependencies with a three-line shell script that calls "cat". Moreover, markdown is confusing to use for basic stuff like links, images (see the sibling comment), and even enumerated lists [0].

every dialect of markdown has an infuriatingly different way of doing basic things that totally breaks your soul if you use a handful of them at the same time.
EDIT:the example you wrote is not exactly the same thing as mine, is it? It seems like it would convert to H1 and H2 headings and both would be displayed in the body.
