Buying and selling root certificates

Steve asked:

Put another way, what's your threat model?

Reminder:

That is THE question you ask first for any security question,
where "security" is everything from door locks at home, parking
spaces at dinner ....to # of guards with M-16's at the data center.

And you should ask it 3-4 times, and see what variety of answers
you get.....

Then ask again at the next review. (Things Change -- just recall
who our biggest ally was in defeating Hitler...and against Iran...)

I see lots of people putting {virtual} vault doors on straw houses.
