Well, hold on.
Maybe there's a way to "eliminate" Congress from the project without disbanding one third of our constitutionally-established government.
See, the problem isn't Congress' existence. The problem is that sometimes Congress provides, as Shrek so delightfully put it, "the opposite of help." So, what if we could minimize this anti-help?
It turns out, we can. The FIST (Fast, Inexpensive, Simple, Tiny) approach does exactly that.
A FISTy project has a small budget, which attracts less interest and oversight from our congressional leadership. A short schedule provides fewer chronological opportunitites for, let's call it involvement (instead of meddling). A small team and simple organization doesn't get spread across multiple congressional districts and states, and voila, that means fewer legislators with a dog in the fight.
These decreases are all appropriate and above-board. It's not a matter of shutting Congress out, but rather of keeping the project sufficiently small that it doesn't require their, ahem, help.
