I believe the troll understands perfectly well.  It's just a point he doesn't wish to acknowledge, because he would then have to concede that Bitcoin exists precisely because of those shortcomings in fiat;  It was designed to alleviate those flaws.  There's a reason why we have a fixed supply and that reason is that fiat depreciates massively over time.

None of these points are in his favour, so he desperately tries to railroad the discussion back to his decidedly abstract (and deeply flawed) notions of value supposedly only existing in debt-based systems.  But he can't control the narrative, so just comes across as a raving kook.
