economy why not thing be cheaper like jp servers

Because the game "creates" gils. The more you play, the more gils you have, the more you'll accept to pay and the more prices will go up.

It's also because some people are stupid.
In FFXI and XIV, people have literally bought gear from an NPC, and put it on the market for twice the price. And it sold !

I was doing that during Betas and when the game was still fresh. I made hundred of thousand with only that.
Then did the same when housing was released. I remember buying 5 stables ( Which are worth 120k each ) and sold them 500k gil each.
