I felt that way until I started using a hair net last year after being a pool owner for 25 years. It catches a lot more stuff then I even imagined. They are/were ( before Covad ) dirt cheap so throw away and replace it.I do not use them and have never saw a need for them. Once a month or so I backwash my 250lb sand filter when the pressure goes up a few psi and the water stays crystal clear. I run the pump in low speed all summer.
Im sure every situation is different and it depends on what's falling in the pool but if my filter isn't complaining I'm not fixing what's not broke.
If it's working for you and fixing a problem you had without them keep it going. How do you clean them?

Gets fine dirt and keeps you from backwashing or cleaning as often saving water or timeIf the filter catches it and blows it out when I backwash why would it matter?
when you backwash you lose your chemicals
chemicals cost money
hairnets are reasonably cheap
socks reduce how often you need to backwash
