Why not just buy the index
It is the best question a client can ask and most advisors answer it badly, by arguing with the premise instead of conceding it.

Concede the premise first
Low-cost index exposure is an excellent default. It is cheap, transparent, and does not depend on anyone being right about anything.
An advisor who cannot say that plainly has already lost the conversation, because the client knows it is true.
The question is what you are being paid for
If the answer is security selection, the index question is a serious challenge and it deserves a serious answer.
If the answer is everything else — the allocation, the tax management, the plan, the behavior — then the index question is about one component of a larger service.
What the index does not decide
Which index. How much of it. What else is held alongside. When money goes in and comes out. What happens in the account that is taxable versus the one that is not. Whether the client stays invested.
Those are all decisions, and none of them are made by choosing a low-cost fund.
Buying the index answers what to hold. It does not answer how much, alongside what, in which account, or whether you keep holding it.
The behavior argument, stated carefully
The most common claim for advice is that advisors prevent clients from abandoning strategies at bad moments.
There is a real basis for that. It is also frequently quantified with more precision than the evidence supports, and inflated numbers get repeated because they are useful. Make the argument qualitatively and you can defend it.
Where the answer is uncomfortable
For a client with a simple situation, a long horizon, a single account type, and the temperament to leave it alone, a low-cost index portfolio is a very good answer.
Saying so is not a failure of nerve. It is the fastest way to be trusted by the clients for whom the answer is different.
What this implies for the fee
If a client is paying for advice, the advice has to be visible. Where it is not, the index question is not a challenge to be handled. It is correct.
