You have asserted that it will be bad, but have done nothing to demonstrate that.
Like Constantine said, if people start harassing someone who's hoarding gold OOC, then report it to the Titans. That's their job.
If people start bugging someone who's hoarding gold IC, to do something useful with it...well, then, what's the problem with that? Why should they be allowed to just hoard gold forever and not have anyone notice or care?
And do you have a good system to separate and indicate that the IC harassment is not extrapolating to OOC?
It would be very easy to harass a player and threat a banishment OOC and claim it to be IC.
And it would be too easy to make a IC discussion overflow to an OOC discussion.
If people suspect about a player hoarding gold there are already systems to investigate and use it IC.
To give power to everyone to keep tabs at other players gold, is too toxic.
You also have a weekly report of how much gold a character receive, and you can see how much gold his family has in the character detail page.
I see no need for a public wealth list.
