I'm not really sure about "He said it was to reduce [...] criminals having to store it". Storage shouldn't be a huge problem - IIRC you can pack about a hundred million onto a standard pallet. Even for Escobar, who is THE outlier here, and assuming he's holding 100% of it in cash, that's about 300 pallets which easily fits into a normal warehouse. If you've got that much money it shouldn't be impossible to keep a warehouse like that clean and dry.

Now, "illicit activity" more broadly speaking checks out to me. The EU stopped printing the 500 euro note because it was primarily used for illegal transactions and money laundering.
