You've quoted this number many times now, and it is completely incorrect. The upload bandwidth required for a full node with eight peers is an absolute minimum of 0.39mbps/mb of block size.
The things you're saying are the kind of things that people who really don't have any clue of the resources required by a node would say. In fact, it's pretty clear you don't run a node, have never run a node, and will never run a node. So your opinion as to the security requirements of bitcoin should be viewed in that context.
