I am all fine with proclaiming that something is not enough... yet? Do we want to go from zero to perfect?
Powell seems to be suggesting that it is totally worthless to show the reserves because it is not enough and it is misleading - but is it a step in the right direction? Do we believe that a company is going to show everything? Every single thing? Where's the incentive to show every single little thing? And where is the verifiability in terms of showing every single little thing? At least with bitcoin, and the bitcoin's blockchain there is verifiability.. and what else has anything close to the same level of verifiability as bitcoin? Everything else requires some level of trust, no?
So I am not sure how you can show everything else without trust, so why not start with the verifiable aspects first.. and then once we get everyone showing the verifiable aspects (if that's even possible?), then we might be able to take some additional steps from there? Maybe some exchanges are willing to show some of the their liabilities, but getting to show everything seems a bit much to expect anyone to cooperate in doing or even to consider that we want that level of transparency? Then when is it going to stop? When are the disclosures going to stop? First institutions (such as exchanges) disclosing, but do the disclosures stop at that point, or then will we require individuals to disclose too?
