When you say plenty does that mean about 1% of the people who actually buy/get stuck with this stuff. I would say that most people are sold these products for commission sake and not to fill a need. There is always the exception.
Ask people that have bought EIA's over the past 5 years whether they are more satisfied with their EIA or the rest of their portfolio. Ask anyone with permanent life insurance that's ever become uninsurable whether they're more satisfied with the product they bought or if they would've rather had a term policy instead. I'll wager a nickel it's more than 1% in both cases.
