Well, people like me appreciate the analysis.
Then analyse this:

Which two were they ?
(Clue: I mixed them - no cryptography involved, so should be easy for you

)
It
will be easy if I put a gun to your head and force you to tell me. Hence the masternode centralization concern.
The gun-to-the-head argument also applies to any coin, including Monero, in terms of giving up keys, access, or association to information.
But the difference is, if you hold up every Monero miner, due to blockchain anonymity, you still couldn't deanonymize the network's keyholders...I think.
Yep, If i remember correctly gmaxwell and andytoshi provided ring signature blinding. So even if 100% of the participants admitted it wasnt them, you cant prove who actually was in the transaction.
