    Since it has a private trans-continental link, and a private
    trans-oceanic link (or a very very long trans-oceanic link around the
    Cape, or a very long multi-satellite path), it will be priced far in
    excess of the costs of its competitors.

I think you don't very well understand international link
costs.   It costs me exactly the same to install a link to
the east coast of the US as it does to the west coast.
Making links that seem to be absurd is sometimes the most
rational thing to do, and can often be cost effective.

There are several links from Asian countries into US east
coast receivers.   Oten, even if perhaps not always, there
are good economic reasons for those.

Any scheme that simply assumes such things won't happen, or
allows for them only in a seriously non-optimal way is not
going to last a very long time at all.   Extreme generality
is a requirement.
