If for pros you're talking about who, Nyl? Rikolo? Rigid? Then you're heavily mistaken. Jackerman here is just 1/1000 of those pros you might talk about and it shows clearly with his own animations. Also I disagree even with the take of "drop school, do porn" because it's not a guaranteed future. Those who can and did it right now, it's because it allows them to (after years and years and years, both of practice and having some stable income). For daz, for example, artist that I know who went full time with NSFW is Squarepeg3D. All of the others are still in the middle. For blender instead, Rikolo, Nyl, Rigid and others just built their own reputation and skill as years went by and not just in a small fraction of time.) and because the market clearly helps them but it's not something that will be there forever. Also as much as I hate it, AI is here, around the corner, and there are already samples that it can do decent stuff with animation. Once it reaches that level that you won't even recognize between an animation made by an artist, by hand, and one made with just some inputs then what? You won't have batshit at hand for searching a normal job because "you dropped school because you thought you could make porn forever". Doesn't work that way.
For example always talking about daz, there was Taboomania that made fucking great content with just Daz that could've been even compared to some of the pro's. And you know what happened? He quitted, because NSFW started to become boring for him and I'm pretty sure he went to school, so now he probably have a job (or maybe he already had one even when doing NSFW). So what if becomes boring also for Jackerman in the future? There are many animator who just got burned out too quickly and some quitted while others, instead, just decided to release stuff but with really slow pace.
As for the obese part, I disagree. Technically speaking they're extremely thick, because using obese morph or something is totally different, and if you think they're just because they have a fat ass, oh boy. Bellies are clearly flat as a surfboard or how it's called and the only extremely huge things are the ass and tits, but that's not being obese, it's like I said thickness. An extreme one for sure.
