There are a few cases for this from my view:

1) Your way of investing relies on an advisor and you don't want an hourly fee. I know that I'm not like this, but I could picture people that do NOT want to do their homework on investing(Just like some people have nannies, mechanics and other experts to do most of the work) and so they PAY someone else to do it. What is wrong in that?

2) There are no good no-load fund substitutes. For example, Fidelity's Select funds come in many different flavours that for some strategies these are precisely what is needed(Of course you can shift money from Select to Select without paying that 3% front-end charge that some people call a load).

I think those are the 2 cases from my view.
