There are places where the incoming work is pretty high volume...so you need a "ticket" system just to make sure it's all accounted for. Jira isn't perfect, but I can't tell if you just generally object to tracking work, or if the particular environment you're in just doesn't need that sort of thing.

And, of course, it's configurable, so any local installation of Jira can be tweaked in such a way that it's a pain in the ass...or not.

I've worked places where there was a high amount of incoming work, and no tracking, and it wasn't healthy. Lots of "squeakiest wheel", "who is working on this?" and other issues.
