I'm sorry but the desire is legitimate and when people want to have a lot of land in RL and be able to afford it from the money they make in their job they usually relocate to less expensive parts of the country where they can get more land for less money.
This is exactly what Amiryu did, she moved from SL to Kitely where land costs less.
As for the price of her items, that's up to the market to decide. An item is worth as much as people are willing to pay for it. If she previously had the amount of business she said she did then there were obviously quite a lot of people who were willing to pay her prices.
A lot of merchants are hurting in SL now even those that sell items for a lot less money. So the fact that Amiryu was hurting as well wasn't necessarily due to the amount of money she charges for what she sells. In any case there are still people willing to pay her those prices, there are just less of them than there used to be.
