"Defensive" BGP hijacking?

Ah, the global system I was referring to was the RPKI as distributed
repository of routing information.  With consistent properties (data
formats, security models, data validation techniques, etc) across all 5

What an ISP does with the RPKI data, interns of route filtering, is always
a local policy decision.    Somehow "global enforcement system" sounded
like a vision where ISPs don't have a choice of how and where to use the
system.  Maybe I read too much into the phrasing.

In the end, I think the issues boils down to if the community has the
desire and will to address the route hijack issue.    If the answer is no,
then no further discussion is needed.  If the answer is yes, then it is
best to discuss and compare real proposals / mechanisms to address the
issue at scale.

I am still interested in some detail on the "tyranny implications".  We
can't address them until we know what they are and how they compare to any
other solution that tries to address the same problem.
