Because (1) someday you HAVE to pay it back and (2) it just keeps getting bigger and bigger and the servicing of the debt gets overwhelming.
As has already been pointed out in this thread, the catastrophic borrowing that America has done is in the entitlement programs. If things keep going the way they are now, the service on that debt will become more than we can possibly pay.
I do not find this answer satisfying. You are presenting these arguments as though they are self-evident. If I learned anything from the housing bubble, it is that not everyone does pay back what they owe. (Please don't interpret this as an argument in favor of default. I am simply pointing out a contradiction.) For point two, please see my reply to Vanadium.
I do also find the phrase "catastrophic borrowing" interesting. Please show that the borrowing is catastrophic, especially in light of my reply to Vanadium, below.

This US currently plays about a quarter of a trillion dollars a year on debt interest. That's money that could go to other areas. That is the entire budget of the State, Education and Labor departments combined. It could fund thirty National Science Foundations or a dozen NASAs.
If I'm reading the information at https://www.treasurydirect.gov/govt/reports/ir/ir_expense.htm correctly, your figure is 15 years out of date. That website says payments for 2014 amounted to $430,812,121,372.05. I did not see any indication that the values presented on that page have been adjusted for inflation. Running an inflation calculation (
http://www.usinflationcalculator.com/) on the 1989 value of $240,863,231,535.71 gives a present day value of $458,648,269,088.55. Effectively, we are paying less on interest today than in 1989.
Secondly, the money can only go to other areas if it is not being used to service debt. While it is nice to imagine a dozen more NASA-like programs, we chose, as a nation, to borrow 18 trillion dollars and spend that money on something other than NASA-like programs. These are sunk costs and the money cannot be recovered. This debt service money cannot be used to fund a dozen NASAs. The reverse is more realistic. NASA's budget and the money from a dozen (or more) similar programs can be taken and applied to the principle and then someday we won't have debt to service. To pay down that debt we are going to have to take the money out of something else (or raise taxes). And not just a little. Deficit spending has to end before we can even touch it.

Footnote: I really do believe that it is preferable to have less debt than more. I guess I just feel that the conversation (on the national level, not necessarily here on this forum) is too emotionally charged. I know that politicians have their favorite lines about debt and deficits, but they convince people with the power of their personal charisma, not objective, rational, logical arguments. I'd like to see more of the later here. (Unfortunately text is terrible at conveying tone. I do not want to be acerbic. I do want to know why you believe what you believe.)
