Schools are one area where there's a lot of money involved, it's a direct service to normal people, and those people actually can do a pretty good job without the school (not saying that everyone can or that it's easy).

Some communities highly dissatisfied with their police attempted to defund and/or defunded their department. That's not a great example because self-service policing doesn't work very well, but it's kinda close.

Ultimately, if you want the voters' money, you need to convince them that you at least won't use it against them. And it's really easy for people to start thinking that it's being used against them when engaging in culture war or political issues.
