As is often the case, it's important to distinguish absolute value (the total net positive or negative created by, say, CBP or law enforcement in general) from marginal value (the additional net positive or negative created when you increase their funding). It's possible and rational to believe that agencies like CBP are (or would be at some level of funding) a net positive in absolute terms, while also believing that they're a net negative at the margin. This is approximately equivalent to the belief that these agencies should exist but should be smaller than they are today. Eliminating service contracts won't "bankrupt" CBP and prevent it from getting anything done, but it will reduce the amount that it can do at the margin. For anyone who believes that CBP funding is a net negative at the margin, including those who believe it's a net positive in absolute terms, this is a desirable outcome.
