Yeah, I don't think the fuel scoop requirement for neutron star boosts is there anywhere, but it is all but required for exploration anyway, and is listed on the Codex too as exploration equipment. Even without opening the Codex though, you'll realise you're missing a fuel scoop very early on, and the route plotter will also tell you when you'll run out of fuel.
So it's kind of like saying that you need weapons for combat. Sure, technically you don't, because you could kill somebody just by ramming them. Same as how you could fly to Colonia without a fuel scoop. Neither method is the common, recommended one.
