Purpose of Buying

The purpose of buying has almost nothing to do with the actual purchase; that's easy. The Clearly Superior Alternative Mandate says the Buyer has to acquire the Best Solution to the Problem, the Clearly Superior Alternative, to survive the Competitive Cliff.
And before the Buyer can buy the Clearly Superior Alternative, they first have to learn deeply what it is, and why it is the best solution to the problem.
The purpose of buying, therefore, is to learn why a solution is the best solution to the Buyer's problem.
