I don't think Satoshi himself would do something so stupid, especially if he continues to hold Bitcoin, he will become one of the richest people in the world in the future. I saw a very recent report where Satoshi is overtaking Bill Gates to become the 12th richest person in the world. If Bitcoin hits the $1 million milestone in the not-so-distant future, then it can be said that Satoshi will be the world's number one richest person. So if Satoshi were alive, he would never do this stupid thing because withdrawing his Bitcoin would really affect the value of his Bitcoin and that could have a negative impact.
He is not stupid if he withdraws and sells some of his coins if he needs money. I also don't think that the reason why he is still keeping his coins is because he wants to be the richest man on earth. I see him as a modest person who dislikes fame. Bitcoin has grown beyond Satoshi. Even if he sells all his coins, the market will still recover
