Don’t forget gas pumps also have to remove and store vapors from the vehicles’ tanks. So I agree, waaaay more complicated. Other than contractors, I’d imagine there are no moving parts on an ev charger.
You have to properly fit the plug into socket and tolerances are small so connector wear is bigger as people most likely just shove it in or force it connecting or disconnecting.
Gas pump for user still can go wrong but tolerances on user just putting it in a bit wrong are much bigger. Tear and wear on gas pump for me is almost non existent.
