Okay, lets not pay taxes, lets pay out of pocket for all that we need. Lets put tolls on every major road, so that when they need to be repaired, everyone who has ever driven on it pays for it. Private streets are paid for by those who live on them. Lets have a schedule to decides who picks up the garbage left on the side of the streets and to mow the grass along the medians. Let us each pay the full cost of educating our children, lets allow us to get sick off of food items such as peanut butter and pay for the investigation into where the source might be. Lets pay for the police protection and decide what criminals we decide should be brought to "justice" and pay for their daily cost in a jail... let us pay for the wars to keep our country safe if we determine by a majority vote that it is necessary. The bill is in the mail. There really is a reason that somewhere along the line they decided that taxation was a necessary evil... do I enjoy paying them, no I don't but since DH and I both have jobs thanks to the Government, my parents and grandparents had private sector jobs that wouldn't have existed had it not been for government contracts.... I just decided that all my tax dollars go to me... rather than the places I would prefer not to think about...
The only thing on your list is that the federal government is even allowed to do under the constitution is war. The rest is left to the states. That was the whole point of our republic--to allow for the competition of ideas among the states. There's a big difference between the feds doing all of those things and the people of individual states choosing to do those things.

But remember, they shouldn't have had those kids in the first place if they can't afford them!
