I am one of the people who would not only question this approach, but be appalled by it. Because what you described is most definitely NOT the point of Values Based Financial Planning™. The point of Values Based Financial Planning™ is to help your clients align their financial choices with their goals and values so they can make better decisions; not just about their money, but their entire lives.
For example, the client's decision to hire you and have a written, comprehensive financial plan which they implement has a profound impact on much more than the client's money. Your job is much less about their money and much more about making sure they do the work required to achieve their goals. When they delegate their financial decisions to you this frees them up to invest this time for the much more important things in life than money.
Check out the Quality of Life Enhancer Exercise® on page 82 of Values Based Financial Planning™ book. I appreciate, however, that you are new to Values Based Financial Planning™, so I can understand how your understanding of Values Based Financial Planning™ will evolve.
