Well it could be limited to be reasonable still. It is true though that 1 person hauling a couple or a few transports in formation might not be so bad (mules). They can only do so much piloting/fighting at a time.
A con would be people would do less runs, but when they do trade there's more at risk.
Also it would make base supply by one person much easier, but if limited to 2 ships per person it might not be so bad.
My reason for supporting it was carriers and docking modules. I'd like to be able to use a snub/freighter and carrier together (probably on a separate computer altogether). You could use the carrier as a slow temp base, and launch from it on your smaller ship to do supply runs or mining. The Bustard comes in mind.
So in groups one person could host a carrier but also fly a smaller ship while just watching the carrier. If it gets attacked you'd just have to choose where to put your attention.
At the very least you could throw a DM on an Adv Train and mine for yourself.
