I'm sure you would, but not everybody is using or likes jQuery. A standalone script such as this one is far more valuable.
Not everyone does, but it is used by over 49% of the 10,000 most visited websites making it the most popular JavaScript library in use today. I'm not saying a standalone is invaluable, but if you're bragging about how it's only 7k, shouldn't there also be a 5k version for people already using the most popular JavaScript library in use today? http://trends.builtwith.com/javascript/jQuery http://w3techs.com/technologie…
That people are now taking the time to create pure JS solutions is nothing but a good thing, and there's certainly no reason why people should have to depend on a third party library if they don't want to.
Finally, your latter point about filesize is a false economy, because a 5k version still requires a 30kb DOM abstraction as a dependency. And since the thing has no external dependencies, why on earth would you want to hobble it with one it doesn't even need?
All these pure JS scripts and utilities get a nice new home in my bookmarks bar, because they're a lot more valuable to me than a shoddy jQuery plugin.
