But it could be very useful to have control units behaving like vending machines. even without them, as stated the stuff you buy will be waiting in a container at the market node you buy it at. Someone could probably still steal that if they can outdo the defenses.

Buying these goods, setting up remote contracts to get someone else to move things for you. Sounds like it will be good fun or lots of agonizing over lost and stolen goods. Makes me wonder how cargo insurance might work.
