I wouldn't bet on it. People like Wright would pay a ton of money for access to those privkeys. Imagine a bad actor gets their hand onto this address and offers access to it to Wright and other Faketoshis for a few million bucks.
Best case would be to publicly post the private keys of Satoshi's addresses. That way, these frauds wouldn't manipulate a part of their supporters. There would still be a significant number of people who would believe that Wright is Nakamoto;
you should never argue with them.
Theoretically if Hal is actually Satoshi, fortunately we really can't make much implications simply because as far as I know we barely know who Hal is, what his interests are, what his political stances are, etc; besides him being someone that's technically literate.
We know enough for Hal and even if they aren't enough, there are people who know more about him. The fact is that you can't prove what's Satoshi's interests due to lack of evident connection between Hal and Satoshi.
