How can any service provide equal benefit to every citizen?
Does the function of maintaining justice provide equal benefit? A standing army to protect our borders? Police to maintain law and order? Courts to resolve disputes? Public education was originally justified - not because everyone had a 'right' to an education, but - because an educated population of voters was a public good that benefited everyone living under our democracy.
It's a judgment call, obviously, but when a government service can't but justified as something that promotes the general welfare of the nation, and instead services the specific welfare of individuals or groups, then it's not something we should be using government to provide. In particular, when we are tempted to look at a given program as something that only some people benefit from, at the expense of others, then we ought to question whether government is the right vehicle for providing that service.
This conflicts with you post at #247. The services you list in your first paragraph are exactly those that tax payers would vote for. Essential services that only the state can provide.
I'm not sure what you're getting at.
My point is that the only services government should provide are those that benefit all of us generally. If we don't think they are doing that, if we think certain programs function merely to benefit some at the expense of others, then we should work to abolish those programs - not use it as an excuse to undermine equal protection with schemes like those suggested in the OP.
