The biggest issue with the launch pads in my opinion is the lack of storage or holding items, your colonists just pile everything directly onto the pad.
In Dwarf Fortress, for example, the trade depot building is only five by five tiles. But the difference is that you can store things inside crates and barrels, and each can hold many many many items inside it. You can easily buy out a whole caravan of goods with your one depot of random fortress made stuff if they're high enough quality.
Until the launchpads get changed, my current "solution" to the problem is to build three of them. I have one pad that holds nothing but silver, a second pad where I pile all of the weapons I don't care about, and a third pad where I store things like food, which is set to slightly lower priority than my hoppers and food storage, so my colonists will always be properly fed before trading away their excess food.
