Just because we believe Satoshi coins are dormant does not mean that they are
For hypothetical instance, Satoshi could have had a child and, perhaps, by the time that child found those keys (after Satoshis death in 2009) they, themselves, may have loved Bitcoin enough to not dump on everyone’s heads
In this instance, Satoshi’s child would be a) not responsible for the creation of Bitcoin, b) the rightful heir of those signatures , c) tax exempt until the spend of those UTXOs
Anyone who attempted to remove those coins from the possession of that heiress would be criminal thieves
This is, of course, a hypothetical but also a much more likely scenario than a quantum theft of Satoshis coins you absolute waffles
