this is why bitcoin is important...
Likewise interest rates on bitcoin would be exactly the same.
Libor is the rate at which banks lend to each other. It wouldn't matter if the contracts were dollar or Bitcoin or seashell denominated. They are private contracts to which the public is not privy. A simpler solution is requiring banks to post their interbank borrowings, nightly, to a clearinghouse.
They don't know the basis of economical science and are stuck in a self-limiting (hence deflationary) monetary base. Not to mention some of the fundamentalism that runs around
Good luck with that
