Hiding the Steem account balance would lead to a loss of other related information about the activities on the platform.

of course. You would not be able to know if the accounts voting you up use their own steempower or have steempower delegated from someone else... however you would be able to see a shitpost and report spam etc... but free and open access to read other peoples savings, sbd, steem or sp information should be kept in a box for those who want it.

Why should I ever need to know what you have on your account or who you sent money to and why? It is none of my business, really.

I agree that security is very important still.

Maybe I need to start up an international private security company and make me an additional income source :)
