> The most natural follow-up to currencies on a blockchain are assets

Natural for marketing-team maybe but not for developers. They only seem natural because they both look like 'value' transfer. But there is a huge difference. The value in-case of currency-use is inherently generated using proof-of-work whereas there is no decentralised way to map a real asset to virtual token.

So NO, none of these 'assets on the blockchain' are decentralized or even need blockchain non-trivially.
