I'd say we team with Satan himself if we could just build a Stanford Torus. Or *anything* that spins. I want to look up and see this with my telescope before I die!
Sure there's difficulty and complexity there, but so many of the problems we have (both biological and station operation wise) are fixed or at least minimized with a little artificial gravity. ANY "permanent" outpost needs artificial gravity. Many industrial processes we'd like to do might benefit from some weight/acceleration too. (and of course some stuff works better weightless- with some spin it's easy to have the best of both
And many of the human issues of long duration flights to Mars or asteroid missions are minimized/eliminated with some spin. People bungie-corded to a tread mill is not a clever solution, it's an embarrassing duct-tape patch. People should be coming back from space ready to walk away and live normally.
Unless some clever physics/math/etc. geek comes up with a magical artificial gravity field, our only choice is to spin.
