Whether or not a particular design is ergonomic depends both on the user and the task it is being used for. It seems that modern web devs consider the audience to be casual viewers who are simply browsing pages on a mobile device. I had more written in my original reply but I removed it since it was nothing more than just me ranting about modern web design.
By the way, I recently found out via a different thread that mobile views are so common and highly values that Google has stopped caching desktop page and now only caches mobile pages. So yeah.
