Snak3 asked about that same earlier, here's my stance on this:

Well, basic fee for transports could be much higher, 25M let's say. No powertrader would lose cash on that.

Each time you use the teleport command, it costs a fee and starts a cooldown, exponentially growing depending on the hold size of the ship.
Snubs/Freighters (<=650 cargo hold): 15 minutes cooldown, 1.500.000 credits fee.
Small Transports/Battleships and below (<=1800 cargo hold): 30 or 45 minutes cooldown, 5.000.000 or 10.000.000 credits fee.
Any larger transport (>1800 cargo hold): 2 hours cooldown, 25.000.000 fee (roughly half of profit made by a one-way ore run).
This way it would actually be more profitable to take an ore from A to B and then return to A with a non-ore commodity than to TP back and pick up ore again. In addition, it can't be done often enough to be profitable in the first place.
