That's probably the most roundabout way to put an article on the web. You are inlining Markdown in an HTML document. Then the browser has to parse and execute 4.5 MB (!) of JavaScript and then it can finally turn that Markdown string into HTML.

HTML documents are a pretty good choice for, y'know, HTML.

Well, if your goal was to increase the page weight from 10kB to 2.2Mb, you surely succeeded.
