I understand what you are saying, but I can't equate your above statement to your desire for goldsinks.
You had to work for your house; you had to save for your house; and presumably, you've saved for other stuff since then.
If you want goldsinks just because you've got more money than you know what to do with... every town has a trash-can.
If you want goldsinks because other people have got lots of money, why punish them for saving their gold?
No you can't.
It's a long time since I did any serious shopping in UO, but with the exception of 1-off event items, what would you say are the rarest/most expensive freely available things? 120 mage/eval? Ornament/Inquisitors/Z-Claw?
A quick run around some shops gives a price-range of +/- 20mil for these. Your lucky weekend camped in Doom or at a Champ is NOT going to get you a suit and a weapon: You'd be lucky to get a single high-end piece for the price of the Ornament.
Ignoring your exaggerstion

, what exactly can a newbie kill? Earth Ellies after a bit of training? 200 gold and a gem? Not exactly raking-in the funds.
This is a point we will never agree on.
You make your first 10K... you spend 3K each on 2 bits of armour better than that you are wearing; 2K on a better bow, and the rest on arrows.
Go out. Kill stuff (perhaps a bit higher than you could kill before). Loot. Repeat until you have your 200mil suit and a 100mil bow.
If this happens, you are trying to run before you can walk; which is a personal error, not a fault of game mechanics.
This happens to EVERYBODY at some time.
I can solo any non-named monster, and have done few bosses with some of my characters.
There will always be someone who can kill xxxxxx quicker than me, but I don't let that bother me.
Nobody is ever going to "win" UO, so I at least, never choose to try. (Which is why I enjoy UO)
