I disagree with part of the thrust of this argument. One of the most hidden things in crypto (despite the transparency of the chain), is who owns, controls, buys and sells coins, in particular related parties to the founders. The disclosure in the regulated markets of insider trades and conflicts of interest is much more robust than in crypto. Yes you can see transactions and wallets, but most of the knowledge is speculations and assumptions, rather than disclosure that can be litigated over. Harder for it to be up to the consumer when founders chose what to disclose, and what to obfuscate. I don't disagree that there are ETNs that work generally as you describe.
