You’re analysis is from the assumption that the spending addicted deficit spending is perpetually normal. The debt limit is a debt limit. It only prevents deficit spending. Government is unwilling to balance the budget and cut other spending before or when the debt limit nears. It’s like saying to you credit card company that if they don’t raise your credit limit, you won’t pay and can’t pay any of your bills. People complain about people not raising the debt limit, but this would be a non issue if government just rained in spending before even reaching it.
