If you can't afford something if the entire US population is contributing, then there's no way you can afford it on your own.
Let's consider your health insurance. You pay a certain amount each month, along with a group of people, into a big pot that is all lumped together. And when you, or any other 1 person, needs help paying medical expenses, that big pot will pay out for you.
Because in a large group, only a few people will need help at any specific time. And because the pot needed to pay out isn't as large, the members of the larger group will pay less on a per individual basis.
that's the underlying premise of insurance.
And we already know that if the entire US population were paying into medical care, it would be cheaper per person in our taxes than it is right now per person paying into private insurance companies.
The same goes for roads, libraries, schools, sewer systems, water systems, garbage disposal, etc.
