If you grind your brakes all the way down to the backing plate then yeah you’re going to mess up the rotors. If you change your brakes around 2mm when it starts hitting the squealer tab you can usually get 3 or even 4 brake changes out of a set of rotors though. It’s not a sure thing but it’s true more often than it isn’t.
Do you live somewhere that you get a lot of snow and therefore a lot of salt in the roads? Rotors can rust and that can make you need to change them more often.
If you don’t live somewhere that rust problems are common though, you might want to have somebody inspect your calipers, or try a new mechanic. You really shouldn’t be having to change rotors every time. That’s a lot of money.
I swap my body panels more often than my rotors (thanks, salt). You should not be replacing the rotors on every pad replacement even in salty conditions.
You need to refinish them on every pad change, and that is the same cost as a new rotor. You can sometimes get by with putting pads on, but if you measure the rotors they are likely out of spec. (not many home shops have a proper micrometer to measure with)

your experinece is different than mine I guess.

I do live in such a place. That may well be a factor.
