Because it was en easier job to make them take cargo space then to make every transport carrying guns slower in thrustering, turning, crusing and so on.

Exactly, right thing would be making each transport slower, but as you said it's impossible to do it, it's just made so that guns take space, easier to do. And no, carrying mounted guns ON the ship should't take cargo space IN the ship.
