When we have robots and automated tech to send a small factory mining robot and convert volatiles on the asteroid into fuel to move it to near the earth, then it will become much cheaper. The cost to send a small surveyor to an asteroid today is only a billion or so. Eventually it will be a bit less, and then it will be a matter of time between landing on one and moving it slowly into an orbit we want.
