Where would the Demand of STEEM come from? (may or may not contain apples)

We are all standing in a big garden,

When we do the apple dance, it rains apples in the garden.
Some will plant their apples in the garden to grow an apple tree.
Next time it rains apples, they will be able to harvest some apples from their apple tree aswell.
Others will sell their apples to people who want to plant even more apple trees.
With time People will grow huge apple farms that produce tons of apples.

At some point people in the garden will want to sell their apples farmed from trees or from apple dancing.
people who don't want, or are not able to start invest in appletrees are not interested in buying apples.
The farmers with alot of apple trees are self sustaining and got abundance of apples and do not need any more apples either.

Then we got investors who are not in the garden;

What investor in their right mind would buy apples for holding onto in the belief they will get more valuable in time, when so many apple trees are planted?
And if there is no buying power outside of the garden, then who will buy all the apples for sale?

Seems to me that the market will be flooded with apples. and the price will fall. with a fall in prices, there will be planted more apple trees in the garden wich in turn will drop prices further.
