You're probably disconnected from limited data plans. The average web page size may be 2.2MB, but this number requires a source. I find it hard to believe that 2.2MB is the average for mobile websites or the actual download payload that mobile phones actually have to pull. The reason is that for mobile websites bandwidth is not the only bottleneck. I assume you're talking about a gzipped payload, along with images. Feed a megabyte of compressed HTML, CSS and Javascript to your average feature smartphone and you'll find that the phone's CPU and RAM can be an even bigger bottleneck than bandwidth. Therefore webmasters have a serious incentive to cut down on the download size. Also popular Javascript libraries, like JQuery and Angular get served by Google's CDN or cdnjs.com and thus cached locally and reused across websites. Even more, static assets on a website get reused between visits, and if say, you're vising a news website regularly, you're not going to receive the whole payload every time, just the HTML. The reason for why I object to your claim is that I've lived with a 500MB data plan for the whole of last year, consuming between 10 and 30 MB per day chatting, reading/writing email and yes, visiting a lot of websites. And I still experience what it's like to have such limitations when in roaming, as I do a fair amount of traveling in Europe. As long as you don't stream videos or music or download apps, it's totally fine.
