You are not being forced to drive on government roads. Create a contract with your neighbors and property owners between you and all places you visit, such that you can pass through their properties. Then you would only need to cross roads. Admittedly, not ideal, but closer to your vision.

I'm assuming your home has never caught on fire. But would you abstain from calling the fire department? What if you were mugged? Do you have a contract with a security firm, or would you call the police?

What about the services you're using but don't think you're using? There are many. Imagine all the contracts and services you'd have to evaluate, sign and so forth to make sure things aren't happening that you don't think about. And then you'd have to monitor the ownership and credentials of all those different firms going forward. What if one of them was bought by a company that has intentions counter to what you intended?
