Earth's economy is unfortunately going to be the name of the game for a very long time to come. When amateurs pay their $20 million to ride the Soyuz, they have to sign a release as well. Asteroid mining will be the same; the problem will be if there is an accident involving property loss when the product is delivered. Hot coffee at McDonalds will be child's play. Imagine the imaginations at work to find a problem with objects [pick one, car motors] made of metal mined from asteroids. It will take a while for asteroid mining to be accepted and get all the usual legal sharks fed.
