That's exactly the reason identity isn't proven the way community wants satoshi to come forward and introduce himself . Keys can be stolen , public identity can't be altered ( well , that doesn't apply to rainbow people ) .
If someone had stolen Satoshi's keys, chances are he would try to liquidate his huge stash (1.100.000 BTC) either to become rich (in terms of USD/EUR) and/or to destroy BTC's reputation (with a sharp drop in fiat valuation).
Also, nobody has revealed Satoshi's identity so far, but HmmMAA claims it's a covert NSA/CIA conspiracy (they "know" who Satoshi is, but they just won't tell anyone, even though we know governments want to destroy BTC).
My knowledge is limited
And yet, you're here to judge others and claim that you have some sort of "technical expertise".
Wanna tell us what's your expertise? What do you do for a living in the real world?
(I don't want to reveal it for you)
