Could you explain a bit more about what you mean by that? My interpretation is that even if you completed a bunch of BTC transactions in a way that allowed you to maintain anonymity, over time, new methodologies or technologies will allow future investigators to trace you as a real person through those old transactions. This? Or something else?

That's the just of it. Many of these public ledgers, like Bitcoin, form a massive transaction graph. Blockchain analytics tools and companies de-anonymize nodes in these graphs by matching real-world transactions to blockchain transactions.
