Earlier quoted context omitted.
Satoshi's wallets have 1.1 million bitcoins, which are worth $56.4 billion at today's price. That would place Satoshi Nakamoto among the 25 wealthiest people on the planet.
The question is why that fact alone would affect the value of this company's shares. Just identifying him doesn't mean he'd liquidate.
In turn that could motivate other governments to heavily regulate bitcoin as they'd see it as a foreign-controlled currency.
That's just fiction, but that's the point, nobody knows for sure who or what Satoshi Nakamoto is, and that's a risk.
