because you are plain too stupid to understand the physics of what I described.
AM particles are most likely to be ionized, which means they can be controlled by magnetic and electric fields.
Is there something about THAT you don't understand?
In every 11 odd tons of interstellar gas there is one gram of AM. Free floating mixed with the cloud of regular matter and they don't touch because the particles are flying around with a lot of space between particles so they don't interact much.
And for every ten billion tons of regular matter flying around in space there is one ton of AM.
Do you have a problem with THAT?
One gram of AM would get like 20 SLS rockets into orbit.
You need to regrow some neurons to increase you imagination quotient.
The physics of gathering AM is clear and will no doubt be used in another hundred years or so when space travel gets over the present hurdles and becomes a commercial enterprise with cheap flights to space.
