I don't think you get it.

Dr. Paul doesn't want anything in particular. He wants the market to decide what is money. If people want to accept paper money, then those who do can. If a person wants metal coin in exchange, then he or she should be allowed to negotiate the transaction using metal coin. If the person wants a digital Bitcoin deposit in trade for a good or service, then that person should be allowed to do that.
The point is Dr. Paul doesn't get to dictate how people transact business and neither does the government. It isn't about what he wants. It is what you want. What you want is freedom. The market decides; Transactions are voluntary and accomplished without the state dictating the medium of exchange.
