You are getting it wrong.

In fact, the stability of the entire game economy is build on the fact that nobody is able to flood the market with thousands of items.

Crafting 1000 items is not really difficult. If everybody would put 1000 pcs on the market, the market would collapse.

Moreover, the more storage space, the less you would sell. That would greatly slow down the economy. Like in the real world in 'times of crisis', everybody would keep all resources till he needs them, so no one would sell.

That's the reason why the retainer space is so limited, and why you cannot easy sell using your alts.

By this, independently of how good you are crafting, your amount of items that you are selling is strictly restricted - and everybody gets the chance to sell.

Actually, the choice QE made is very well balanced. The market is very active. The prices are moving quickly and everybody can find items to sell at good sell/production cost ration when doing a bit of research.
