The transparency does pose some issues. I recently read a post by a whale @fyrstikken, mostly focused on the safety part of people knowing how much money you have, an issue that will just become bigger the higher the Steem price goes. Here's a link :

In my own opinion I think it's hard to hide the wealth on a platform that is built on transparency. Sure you can make other accounts and hide money there, but then you can't really use it for posting, so the money will kind of sit there, unless of course you delegate, that could be an option.

If a mechanism was developed where you can't see the amount in someone's Wallet that wouldn't stop people from figuring it out by counting backwards when you vote.
