It depends on factors. Where do you live? What kind of account do you have? And more. So while I cannot say 100% for every Steem account that this will matter I can say for certain for some account holders it matters a lot.
It's not safe in most cultures in most parts of this world to flaunt wealth. It's definitely not safe in the US/UK to do it. It may be safe in places like Japan and some parts of Asia. So it depends.
I think the issue is significant enough to hinder adoption by deep pocked westerners. I think in Asia it will not matter so much.
I can see that being a steemit superstar and flashing your wealth can e problematic in some parts of the world but people who care about that can stay annonymus.
No one is forcing them to put their public info here or reveal their identity.
