The big problem is that the Villa of the Papyri is underneath modern buildings. That doesn't mean that excavation without demolition is impossible (see the Scavi underneath the Basilica of Saint Peter), but it makes things far more difficult.
If the prospect is very high to multiply by several times the total remaining classical works, I doubt that the money will be particularly hard to find ?
David W. Packard (HP heir) has been trying to throw money at doing this for years, so the money isn't as much of an issue as you'd think. The larger issue is that the locals don't want digging underneath their buildings, no matter how careful the excavators are. Also, all the money that would be necessary to excavate has made the project a target for the mafia who wants to get their share.

This sounds like the money IS a huge issue. How expensive can it be to buy out the locals? We're talking about priceless cultural artifacts
