Well it's not a stupid idea at all, that when you pay taxes, you could vote for the 3 or 4 topics that you want support in priority, and they get allocated a more budget in proportion or something like that.

This could even increase support of people to pay taxes (reducing fraud) as the taxpayers would know they would be supporting projects in line with their vision and lifestyle.

I get the idea, but this is basically just admitting that our representative form of government doesn't work. Ostensibly we control our taxes already by who we vote for.

That sounds like it would bring even more political divisiveness and injustice to the US.

Rural sprawl significantly increases overall infrastructure costs. Their taxes are already being subsidized by more urban tax payers. Those rural areas can't afford to maintain what they have.

Sounds good. Might even bring some accountablity

Yes.

Further, they should be forcibly blocked from using any services they refused to pay taxes for. No highways, flood protection, low food prices, or access to the global trade network for you!

Except if they purchase a subscription to these benefits through one of the two companies (same parent company) that provide them. The subscriptions are of course competitively priced, since they only have the best interest of their customers at heart.

I find it's helpful to create a monopoly on purpose, and then give that monopoly for a service an additional monopoly on violence. Then, if someone doesn't want to use the monopoly, they can just send men with weapons of war to force them to fund the monopoly at gunpoint.
