The only reason this ridiculous gravity pull method is even considered is that the asteroid may actually be a loose pile of rocks or snow/dust, not holding together strong enough to be pulled directly by pushing/pulling in one spot. Actually I see one problem with this method, the mass ejected from the station keeping thrusters would hit the asteroid and cancel the effect of the gravity pull. It's like getting into a basket and trying to lift yourselves up. They would have to fire multiple thrusters at an angle away from asteroid lowering the effectiveness of it all which is unfortunate because this is what translates into actual orbit change of the asteroid. It may be harder than it looks to stay very close to a big asteroid and keep position in a way that does not affect the asteroid. For gravity effect you need to be as close as possible, while it becomes harder and harder not to hit the asteroid with your thruster plumes. Maybe put the engines on a long cable so that they are far enough to fire at a smaller angle and let the heavy part of the spaceship hang towards the asteroid?

They can't have it both ways.

Oh but they can! They always pick what is best for them, arbitrarily.

Just selling digital copies is not a viable way of making money.

Value of a digital copy for everyone else equals to value of work you put into making it, which is ZERO.

Even if you factor in the cost of making the initial original, because you can make infinite copies, it is still ZERO.

How many sane people would pay for something they know cost you nothing? Pay you over and over again for the same work you did?
When they know they could make the copy themselves for zero cost?

It is like you picking a rock and trying to sell it to someone who saw you do it for a ridiculously high price, with plenty of other rocks lying around.

Making laws so that only you can do it to make this fly is not fair. Why should you be allowed to make money for free while everyone else has to work?

Forget about selling digital copies as a way to make money. Sell licenses. Sell tickets. Just dont sell copies please. Stop already. Stahp!
