If a person does not want anonymity they could simply publish their full name and address along with their BitShare address on a forum somewhere.
If my account takes a loss in a tax period, I may want to claim that loss against other gains.
I wonder if posting my name and address on a forum associated with a bitshare address would be sufficient proof of that ownership?
What stops others from posting similar information on another forum? Or just copy and paste my information with changes to point it to them?
The goal is to support provable ownership by a unique identity so that it is not only usable by anonymous, yes? (That risks making it a criminal enterprise and invites opposition unnecessarily.)
Users may not take advantage of the identity feature, but it should be available to those that need it.
If you want to do things 'legally' then I suspect you can always go through a centralized exchange that will vouch for your ID.
