I mean, yeah, that's all WHY people WANT to DM, but their success or failure at it can come about because of its relative difficulty. I think we can all agree (as much as we can agree upon anything at all) that there are tools for the job that can make it easier, and those tools are not always presented well, when they are presented at all.Call me a cynic, but I honestly do not believe it is the ease or difficulty of DMing that makes someone choose to do it. People DM mainly for other reasons-- they like creating stories and outlines and plots, their personality is such that being the one "in charge" comes naturally to them, they want to play bad enough that they will run a game just so there is a game to be played, they are a multitasker at heart and enjoy the challenge of juggling many balls at once (or as @overgeeked mentioned they have ADHD and are just wired to perform better doing many tasks rather than just one), or they have played enough that they've developed a very specific or idiosyncratic preference towards gaming and running games is the only way to assure themselves they can get the type of game they want.
What those tools ARE, of course, would be up for debate, as usual.
