 rising the block size

Geir,

In the scenario below, you argue that the current 1MB limit would lead
to "constantly full" blocks. If the limit is increased to say 1.6GB
then a government or banking group may choose to utilize 1.5GB of the
capacity of each block (and pay fees or not) for their settlement
network. Then how did upping the blocksize remedy anything? Or is this
use-case not plausible?

I would like to ask you, or anyone on the list: when we say that
mining secures the network, what does that mean?
