So you do have trade and an economic system.
There are times when
it is more profitable
to trade than steal.
It's a struggle, though. Asking
a sqid not to steal is like putting a marshmallow in front of a kid and telling him he'll get two if he waits.
A human child will either eat the marshmallow or wait. A sqidling would eat the marshmallow, leave the room to find where it came from and then run off with the rest of the bag.
