I get that he may have been in a very small team who chose to collectively call themselves Satoshi Nakamoto.

However David Kleiman did not die extremely suddenly - it is hard to believe that he would not have passed on pass phrases to either trusted members of his close family or even trusted close team members of the Nakamoto team and instead chose to kill his $millions of pounds worth of BTC from the early mining days. The only other explanation would be if he only had one wallet from the early days (I find this implausable for someone developing the very fist blockchain coin with testnets and then production testing etc) and had inadvertently lost/forgotten the passphrase.

Even if this unlikely scenario were true - The BBC and The Economist are not tabloid rags. They would not print stories stating that Craig Wright is Satoshi Nakamoto if he was merely claiming to be part of the original core team who mined the first BTC genesis block on the production network.

This leaves us with two possible scenarios;

1: Craig Wright is a disingenuous Walter Mitty type with ambitions to 'take over' the future direction of BTC.

2: Craig Wright was nobbled during the period of the raids on his house and given no option by the authorities except to stand as the 'head' of BTC and do their bidding. Unfortunately for the authorities he was not close enough to the original core team to have the tools at his disposal to 'prove' his case.

All in my humble opinion, of course!
