I don't. I'm saying using the blockchain for log-in is preferable to using a TTP for log-in.
In general the blockchain should eventually be able to remove the need for any type of TTP, even for delegation. I think Steemit Inc would do wise to keep close tabs on the Agoric developments and maybe work with Agoric to make STEEM bleading edge with respect to implementing cap patterns for rights and delegations. In the meantime, only using a TTP when delegating, not when logging in, should I think be the first step away from the IMHO outdated concept of TTPs.
