Added Complexity Justification

There exists a method known to solve a problem. However, it is not clear why the method is necessary to apply or whether using it justifies the added complexity. For learning purposes, provide a practical example that demonstrates a problem in detail without using the said method. After that, provide an example that incorporates the method, allowing the problem to be solved. Describe the reasons why it is beneficial to do so and suggest simpler alternative solutions, if necessary. Format the response in Markdown. The question is:

Five whys

Given a statement, apply the "Five whys" technique. For each of the five questions, provide a detailed answer, nothing more. Format the entire response in Markdown, alternating questions and answers. The statement is:
