That sounds more like an explorable reason, though I've a hard time to think about how someone could use this to fight against old coins confiscation ideas.
Well, some countries have weird law systems or, more likely, I lack severely legal imagination.
As I've already written, it doesn't look like much of accidental transactions. Though they were broadcasted in a short amount of time, all five transactions sat for somewhere between 56-57 minutes in public mempools, of course, unintentionally, because blocks come somewhat unpredictable.
I checked times again and to me it looks like the transactions were broadcasted little time after block #950958 was confirmed (my node saw this block at 2026-05-25T13:01:29 UTC).
Block #950959 came in at 2026-05-25T13:30:36 UTC, but didn't confirm the transactions. Roughly 26-27 minutes to correct any accident by replacing the unconfirmed transaction (RBF was enabled, Full-RBF supported by mining pools).
Next two blocks took about another 25min to appear, but again didn't confirm the transactions. Finaly block #950962 confirmed all five, which my node saw at 2026-05-25T13:59:17 UTC (blocktime in header is 2026-05-25T13:59:23 UTC).
I wouldn't necessarily conclude that amount of bitcoins moved correlates with knowledge how to handle mistakes, but it's likely no noob who has done those transactions. OK, don't judge me, it's speculative. As some, maybe most, coins originate from around 2014, IIRC, the "owner" isn't likely a newbie to Bitcoin.

I don't think or believe this could've been a joke, so maybe we can stear this topic to some better speculations what the purpose could be.
I appreciate outside-the-box thinking like philipma1957 did.
