But it doesn't say you can't either.
Here's how it works:
The game rules specifically state that you cannot boost or barrel roll off of the board or onto asteroids/debris. The rules for TB make a specific exception to that rule and allows you to boost your opponent onto asteroids/debris with TB. That is the only exception to the rule. If they intended you to Tractor Beam your opponent off the board they would have specifically included that language to make it work. They did not include an exception for that therefore you must abide by the rule that says no boosting or barrel rolls off the board.
You are not the first person to ask or argue this point. This interaction has been established for quite some time given the TB was originally spoiled 2-3 months ago. That's why your arguments were likely met with such hostility. Asteroids yes, off the board no. There was no oversight. This is how the designers intended it to work. Hope that helps.
