Your idea does not address the economy; it just makes it easier to organize your gold.
Here's my idea for adjusting the economy in a positive way (I won't say it "fixes" the economy):
1) Reduce all gold by 99.9% (1,000gps = 1gp) rounding off to nearest full gp (any gold stacks below 500 gold disappear).
2) Add feature to vendors to allow the owner to auto re-set all prices to .1% of what they previously were (rounding up).
3) Leave pricing the same for all basic items on NPC Vendors, but reduce the price for all resources, lootables, and non-basic items (i.e. Shadow Iron Shields), which will also fluctuate based on supply/demand. Any items bought from NPC Vendors before the change could only be sold back for 1/1000th the original value (to stop folks from buying tons of NPC stuff before the change then sell it back after).
4) Either remove loot gold or reduce it to just a trickle (1-10 gps) on everything except Level 5 Fame Creatures (Balrons, Ancient Wyrms), Bosses (mini and full) and Champions. Another option would be to start all creatures with 0 gold. The longer they go without being killed, the more gold they have. The rate of increase would be based on Fame or difficulty.
5) Remove or greatly reduce gold earned from turning in BODs.
6) Leave housing prices high.
Item 3 stops players from exploiting vendors for gold and also keeps mundane items relatively high.
Items 4 and 5 make gold much harder to accumulate, thus gold value stays high. If there are other ways to easily accumulate gold, they should also be made harder (such as buying cloth, cutting it into bandages, then selling the bandages to a healer at a profit).
Item 4 would also get rid of scripting Gold Farmers.
Something else they should implement is global NPC vendor pricing. Right now on Napa, you can buy ingots for 20gp each in Minoc, then sell the same ingots for 55gp in Luna. So 500 ingots can net you 17,500 gp in less than a minute. That doesn't make sense especially since we can recall or sacred journey almost anywhere we want to go. The price for any item should be the same regardless of where you buy or sell it.
Item 6 makes housing valuable again. Sure. Someone could sell their house for the gold, but then they wouldn't have a house and wouldn't be able to afford to buy another until they save up the gold again. This could be exploited by creating trial accounts, but that could be thwarted by not allowing trial (non-paying) accounts to have houses which they are about to do.
This isn't just about removing 0's. It's about making a gold piece worth something again. Right now, 1,000 gold isn't even worth looting.
