If the Banks succeed in taking over Bitcoin, they will have access to networks that can handle more than 1MB of data every 10 minutes*. With 100MB blocks, Bitcoin can handle up to 700 transactions per second (CPU might start to become the bottle-neck).

Bitcoin appears to be the first secure network application in the history of mankind. It does not have to be imposed by force: because it is far superior to what has come before.

*Note: My full node uses about 100GB of it's 300GB cap every month (works out to less than 1Mbps).
