v4v is transactional, but not in the same way of setting prices and telling the person "take it or leave it". That's the transactional nature of something like an employee/employer relationship, "Here's some work, now pay me my agreed upon wage". No, it's transactional like a marriage. A husband takes care of his wife because he loves her, not because he gets something out of her, and she returns the love in kind. It's an exchange of value, but one built on love, not negotiation.
