I know you are trying to cherry pick and you are technically correct, but my point remains. Why do states rely on that? I mean, who turns down free funds right? Rarely does it happen.
The point is that they had the option to turn it down, knowing fully well that our federal government already spends enough so as to continue driving itself deeper into debt, yet they did not turn it down (in most instances). So if the federal government has put money and other resources into developing and maintaining states, should the states be obliged to pay that debt back upon secession?
There's obviously an argument to be made regarding federal funding that has been "forced" upon states, but I honestly don't know how the amount of that funding compares to the amount of voluntarily accepted funding. Nor do I know how much of the total federal debt the voluntarily accepted funding makes up, although I assume it's a very small portion.
The ultimate point that THS made and with which I agree is that the federal government didn't do this on its own. We can talk about the separation of state and federal governments all day, but there is a monetary tie between them that causes the federal government to support state governments in many ways.
Although the states' acceptance of federal funding is probably a small portion of the federal debt, and although the states' ability to receive federal funding is a symptom of a bigger problem on the federal level, the states still played a part. To me, requesting secession is refusing to accept any responsibility for the financial situation, and is not a viable solution for the state governments that are currently reliant on federal funding and have no realistic way to create a separate, financially fruitful government entity.
