There's a third possibility not many seem to want to consider; he's telling the truth and it turns out the real Satoshi isn't the benevolent genius everyone imagined him to be. He's a fuck up con man.
I totally agree with you. The community doesn't want to believe there's even the possibility that Bitcoin was invented by a scammer, because by implication, it would mean we were scammed. It could just be this is the tech community's version of crop circles (https://en.wikipedia.org/wiki/Crop_circle) or tree fairies (https://en.wikipedia.org/wiki/Cottingley_Fairies). Very smart people fell for those hoaxes at the time, and put a lot of effort into explaining why it wasn't a hoax - even when the original hoaxers revealed themselves.
Perhaps Wright paid somebody to develop the Blockchain technology. Perhaps he developed it himself and then lost the original key, assuming the project was worth nothing. Perhaps he was one of a group of people, and that group has now decided to nominate him as the frontman for the technology, perceiving that the whole Satoshi thing is holding back its development.
