Why not use Toxiguns all the time instead of heavier guns and such?

Because the ammo for the Toxiguns is time consuming to mass produce and you'll need more time for other stuff, like building your own ships for instance.

Second to that, if you end up in a building with agressive humans like in the Slums or against an agressive corporation, you won't do any harm if you don't have the big guns on you. I don't like bothering myself spotting such places, then switching weapons before going there everytime so since having a all around issue equipment is easily possible I jumped on the occasion.
