As to whether or not your premise is spiritual, and not political, I would say.......yeah, right! You're not going to catch me in your cute little trap, OP.
Not a particularly good example. While it seems to me that user-fee Tollways work just as well as Interstates, the fact is that the Gasoline Tax more than pays for all Highway budgetary requirements. Indubitably, the Government brings vast quantitiites of Graft and Corruption into the Equation, but by comparison to other Government "programs", the Highway system is a model of Ethical administration. The User of the Highway pays for the Service (with his gas taxes), the Non-User of the Highway does not pay for the Service (since he purchases no gasoline).
User pays. Non-User does not pay.
If we have to have Government programs, let them be structured thusly.
By contrast, have you offered to re-imburse the Property Taxes stolen from all your fellow Christian home-schoolers and private-schoolers to subsidize your kids Public Schooling?
Because as long as any Non-User (private-schooler or home-schooler) pays even one dime of compulsory taxation into a Government Schooling system which he does not use and does not want, anyone who supports the Public School system is just a thief dividing spoils.
Belly up to the bar, there's plenty of grift for everyone. It's free to the public, thanks to all the people who are compelled to pay for that which they do not use and do not want.

This is a straight, uncomplicated, and utterly simple Eighth Commandment issue. Nothing more, and nothing less.
