For me, the sad thing is in how common this point of view is. Many people assume that these vital services can only be adequately supplied by the government. Few people ever try to justify this assumption and, in my experience, none have truly succeeded. Indeed, I believe that without taxes we would be overall more safe and better off.
Arguing that those complaining about taxation are unaware of its function is akin to accusing the Bitcoin developers and early adopters of being unaware that banks and the government need control over our money to help fight crime and manage the economy. There are plenty of people here that not only understand this but are poised ready to tear such a comment apart.
Granted, there exist plenty of taxation's critics that don't know what they're talking about and could even be won over by your trite observation but it's beyond insulting to assume that all critics have spent fewer than 60 seconds considering their position.
You got raped? We don't care, since you can't afford our service.
