Okay, you're clearly missing the point here. Sure, you can upload them videos and put them in a page somewhere, hosted by a web server somewhere. But why would you do that?

The cost of keeping your videos accessible are higher than keeping a typical blog accessible. Storage and bandwidth are obvious ones. How do you get ad networks to monetize your videos, if you want to? How'd you get people to discover your videos, as they are not first-class citizens of a search result page? Where do people even watch videos these days? Everything is on Facebook or YouTube.

You can somehow self-host your videos, but even if you manage to do so, your original purpose for doing it in the first place won't be met, it simply isn't worth it.

Contrast this with Medium, where there are not as many benefits for letting them benefit from your content. Hosting plaintext or markup is trivial, easier to maintain a blog with stuff like Wordpress than to learn how to manage your own server directly to optimize for video. There are a lot of aggregators like HN and Reddit that are populated mostly by blog content, and even if you don't resort to these, your pages are first-class eligible citizens in search results.

Heck, even the policy regarding discussions not being actively shown may hurt your specific type of content. Moderation is tolerable with Disqus, for example.
