I don't agree. The reason you provided that you think will probably kill Bitcoin is also the very reason why Bitcoin came into a certain point of popularity. How can it kill Bitcoin when in fact it is the very life of Bitcoin? The reason why Bitcoin became the Bitcoin that the whole world came to know of is that it is decentralized, anonymous yet transparent, and digital. These the sources of convenience and efficiency of Bitcoin.
