I disagree that you can avoid using these services, because I don't think that things like public schools are a service only to their direct recipients. Even families that can afford private schools for their children benefit from living in a nation with a high literacy rate. I'm not a 'customer' of my city's social services, but I benefit from having fewer people bottom out and end up on the street.
I don't see the benefit to anyone else to having someone be educated. And if you don't use social services there is no benefit to you (not saying we shouldn't have any, but it's wrong to say they directly benefit you.)
Yes you can go far enough and find "indirect" benefits to anyone for anything, but you have to stretch it quite a bit.
