@amarand well at that point you could call it forced or required donation for the privilege of living somewhere or buying something.
I do think if we go off that mindset that everyone should be free to choose where their tax dollars go. You want yours to go to pot holes? I want mine to go to parks. Let people choose. Everyone contributes and it's going towards what they want...even if they're the only ones. Once something is funded, you choose your next priority.
@amarand none of this is to say that people won't be dicks about how they spend. They make their bed. I just think it's tough to say "you should donate here instead of there".
