Why it would be unreasonable to declare an integrity constraint to that effect?

Mainly because integrity constraint operate on row-basis. Transactions then again ensure that the operation is completed as a whole even when multiple commands are affected.

But neither of these guarantee that the total sum is unaffected when money is transferred. If this would be a single table operation, a trigger could be utilized to do that check.
