If people want it they will pay for it. If they're unwilling to pay for it, they don't want it. The question is does its historical significance matter to enough people to justify the cost? I'm guessing the answer is no.
The "people" as a whole are dumber than a sack of hammers when it comes to anything related to history or heritage. You don't consult idiots. You do what must be done. I would transfer every dime set aside for Libya and other make- believe friends and use it for domestic needs. There's about 300 billion dollars in waste or excess every year, all of which comes with no serious penalty for the individuals and organizations that are so inefficient.
