This is a gross misrepresentation. When you have a master key, theft of
the master key compromises the entire system. When you don't have master
keys, theft of a key only compromises the entity associated with that key.

You can have a manageable system without relying on master keys or key
escrow. Kerberos has been doing it for decades.

"Merely". And how, pray tell, are YOU going to know if your private root
certificate has been compromised when X.509 lacks a mechanism to detect
root certificate compromises?
