The physics don't work to bring this stuff back to LEO. We’ve got to use the atmosphere to slow us down.

How are you planning to do that in future missions? Sending up a a capsule or heat shield for sample return, or is the ultimate goal to return a larger mass and lose some?

Pre-built sample return has been proven to work with another asteroid in a small way I guess, the Hayabusa mission.
