Lolis are small and cute, possibly taboo, you can pick them up, they're more associated with innocence and purity, and when they're not so innocent there's a nice contrast between their appearance and behavior. They can blackmail you into sex the way only a loli can, and taunt you for finding them attractive in the first place. Lolis can have just one of any of the traits you're listing, so for fetish discussion's sake, I'll assume you refer only to pure common lolis, the most popular kind. Most lolis aren't true flat. They have some amount of small or budding breasts, which are usually considered extra springy. I myself do enjoy true flat, but it's not a fetish I can justify with logic. Generally the cunny is closed tight. Roast beef may be a primarily 3DPD thing, but it still shows up in 2D, and shows up far less with lolis. Same for NTR/cheating. Lolis are shown far less often committing these acts than cow tits. There's often the size difference, but with straight loli shota, there's often exploring sexuality together for the first time which is usually fairly saccharine. That's not to say an innocent virgin bombshell isn't something that happens, but it's more common with loli, fits more with a loli's innocent appearance, and you never get a shota figuring things out for the first time paired with an innocent bombshell. Maybe a stacked virgin, but she'll always know a fair bit more than the shota. lolis, and by extension shotas, are liked both in and outside of hentai for the one of the same reasons high school settings are popular. Younger characters are more believably undeveloped, and thus it's easier to believably develop their character. This ties back into fetishizing discovery of sexuality. I think the character's internal thought process and agency as they develop is important, which is why despise mind control and generally dislike rape, but I digress. You say there's no ass, but like the small chest, there usually is some ass. When they're drawn with pure Hank Hill ass, I don't like them. You can't fetishize fucking raw as much as possible before the first period hits with a non-loli. I could ramble on, but this really should be taken to a fetish board like /loli/ or /h/.
